Denmark has had many different legendary and historical dynasties and kings, the heirs of one dynasty or king are not necessarily the heirs of other dynasties and individual kings.

This post is a list of the heirs of Kings Erik V, Erik VI, Christopher II, and Waldermar IV of Denmark. It started out as a list of the heirs of King Waldemar IV, but I thought I should make a list of the heirs of his father King Christopher II just in case there were no descendants of Waldermar IV, and it turned out that I had to go a generation farther back to King Erik V to trace the heirs of those kings.

1. King Christopher II of Denmark (1276-1332). King of Denmark 1320-1326. Deposed. Father of:

[Erik Christofferssen (c.1307?-1332), son. co king 1321-1326, deposed. Died a few months before his father. Childless]

2. Otto (died after 1347) Second and oldest surviving son of King Christopher II. Duke of Lolland and Estonia, Knight of the Teutonic Order. No children.

3. Waldemar or Valdemar IV (c.1320?-1375) Atterdag "Another day". Brother of Duke Otto and third son of King Christopher II. King of Denmark 1340-1375. Grandfather of:

4. Duke Albrecht IV of Mecklenburg (d. 1387/88). The son of King Waldemar's older daughter Ingeborg. His first cousin Olaf was selected as King of Denmark in his place. Albrecht IV was childless. Brother of :

5. Euphemia of Mecklenburg (d. 1400). Married but childless. Sister of:

6. Marie of Mecklenburg (1363/67-1402). Sister. Married 1380 Duke Wartislaw VII of Pomerania. Mother of:

7.Erik Bogdislaw (1381?-1459). Son. Duke of Pomerania. King of Norway 1389-1442. King of Denmark 1396-1439 and Sweden 1396-1439. Deposed. Uncle of:

[Christoph (1416-1448) Sister's son. King Christoffer III of Denmark 1440-1448, King Christof of Sweden 1440-1448, King Christof of Norway 1441-1448. Childless.]

King Christoph was the only child of Katherine of Pomerania and Count Palatine Johann of Pfalz-Neuburg to survive childhood. Katherine and King Erik were the only known children of Marie of Mecklenburg and Duke Wartislaw VII of Pomerania. It appears that ex king Erik of Pomerania was the last surviving descendant of King Waldemar IV.

King Christopher II of Denmark's older daughter Margaret (1305?-1340) married Margrave Ludwig of Brandenburg (son of Emperor Ludwig IV), and had a son Matthias who seems to have had no children. His younger daughter sees ms to have died unmarried. King Christoher II had two illegitimate children, but they would not be eligible to inherit the throne and I don't know if they have descendants to this day.

So there are no persons who are legitimately descended from King Christoper II of Denmark, and thus could be considered the heirs of King Christopher II while not also being heirs of any earlier kings of Denmark.

King Erik V "Kipping" (c.1249?-1286) of Denmark, the father of King Christopher II, seems to have descendants to the present time. His oldest son, King Erik VI "Maendved" (1274-1319) is listed as having four sons who died childless before him, and no other children. Thus Erik VI's heirs would be the same as the heirs of King Christopher II whose descendants died out in 1459. Their brother Waldemar died in 1314 without children. Their sister Margaret (died 1341) married King Birger of Sweden in 1298 and had a son Magnus who was beheaded in 1320 leaving a possible illegitimate daughter. Anyway, Margaret may have been younger than their sister Richiza (died 1303/08) who married Lord Nicholas of Werle (d. 1316). Their daughter Sophie was the great great grandmother of King Christian I of Denmark, Sweden, and Norway, but their son Johann III of Werle (d. 1352) was the father of Nicholas IV of Werle (d.1354) the father of Johann IV of Werle (d. 1374) who died childless.

Lord Johann IV of Werle had two sisters. One, Mechtild (d. 1402) married Lorenz of Werle (d. 1393). Their first son Balthasar of Werle (d.1421) was childless. Their second son Johann VII of Werle (d.1417) was childless. Their third son Nikolaus of Werle (d.1401) was childless. Their fourth son Wilhelm of Werle (d. 1436) had a daughter Katarina (d. 1475/80).

8. Katarina of Werle (d. 1475/80) was the heiress of King Erik of Pomerania if her grandmother Mechtild was the older sister of Lord Johann IV of Werle. Katarina married Duke Ulrich II of Mecklenburg-Stargard (1438?-1471). Their daughter Elizabeth was a prioress and died childless. Their other daughter Ingeborg (d.1509) married Everwin II, Count of Bentheim. Apparently there were two counts Everwin II of different Bentheim branches at the same time, so I will not try to trace Ingeborg's descendants now.

9. Ingeborg (d. 1509) possibly the older daughter of Katarina of Werle and thus the heiress of Denmark.

Lord Johann IV of Werle had two sisters. His other sister, Agnes (d. 1383) married Johann VI of Werle (d. 1377) and apparently they didn't have any children.

Going back a generation, Nikolaus IV of Werle (d.1354) had a sister Mechtild (d.after 1361) who married Otto I, Count of Schwerin (d. 1357). They had a daughter Richardis (d. 1377) who married Duke Albrecht III of Mecklenburg (1340-1412) who was also King Albrecht of Sweden. They had three children and their daughter Richardis (d. 1400) married Johann of Bohemia, Margrave of Brandenburg and Duke of Gorlitz. They had a daughter Elizabeth (1390-1451), Duchess of Luxembourg, who married twice but had no children.

Going back another generation, Richiza of Denmark and Lord Nikolaus of Werle had a daughter Sophie (d.1339), who married Gerhard III Count of Holstein-Schauenbuerg (d.1340). Gerhard and Sophie had a oldest son Henry II Count of Holstein-Rendsburg (1317?- 1389) who had an oldest son Gerhard VI of Holstein-Rendsburg (d. 1404) who became Duke of Schleswig in 1386. Duke Gerhard of Schleswig had sons Duke Heinrich IV of Schelswig (1397-1427), and Duke Adolf XI of Schleswig (1401-1459), who were childless, and Duke Gerhard (1404-1433), who had twins born in 1433. The boy twin Heinrich drowned mysteriously and his siter was a nun. Duke Adolf XI had a sister Hedwig (1398-1436) whose first marriage had no children and married secondly Count Dietrich of Oldenburg (d, 1440) and their oldest son became King Christian I of Denmark and Norway. King Christian I (1426-1481) was the father of:

10. King Johann I of Denmark, Norway, and Sweden (1455-1513). He became the rightful heir of Denmark in 1509 when Ingeborg of Mecklenburg-Stargard died, unless she left Bentheim descendants. Father of:

11. King Christian II of Denmark, Norway, and Sweden (1481-1559) Deposed in 1523. Father of:

12. Dorothea of Denmark (1520-1580) married Frederick II (1482-1556) elector Palatine. No Children. Sister of:

13. Christina of Denmark (1521-1590). Sister. Married first: Duke Francesco II of Milan. No Children. Married second: Duke Francis I of Lorraine (1517-1545). Mother of:

14. Duke Charles III of Lorraine (1543-1608), father of:

15. Duke Henry II of Lorraine (1563-1624). Father of:

16. Nicole (1608-1657) rightful Duchess of Lorraine. Married her first cousin Duke Charles IV of Lorraine. Childless. Aunt of:

17. Ferdinand Philippe (1639-1659). Son of [Claude (1612-1648), sister of Nicole. Married her first cousin Duke Nicolas Francis of Lorraine.] Childless. Brother of:

18. Duke Charles V of Lorraine (1643-1690). Father of:

19. Duke Leopold Joseph of Lorraine (1679-1729). Father of:

20. Emperor of the Romans Francis I Stephen (1708-1765). Father of:

21. Joseph II Emperor of the Romans (1741-1790). No surviving children. Brother of:

22. Emperor of the Romans Leopold II (1747-1792) father of:

23. Emperor Francis II & I (1768-1835) Father of:

24. Ferdinand I, (1793-1875), Emperor of Austria 1835-1848. Childless. Brother of:

25. Archduke Karl Franz(1802-1878). Renounced his rights to Austria in 1848. Father of:

26. Emperor of Austria Franz Joseph (1830-1916). Grandfather of:

27. Archduchess Elizabeth (1883-1963), daughter of Crown Prince Rudolf (1858-1889). Married first Prince Otto Wieriand of Windisch-Graetz. Mother of:

28. Franz Joseph Prince of Windisch-Graetz (1904-1981). Oldest Son. Father of:

29. Guillaume Prince of Windsch-Graetz (born 1950). Born 1950. Unmarried. Brother of:

Stephanie (born 1939). Sister. Married Dermott Hugh Blundell-Hollinshead-Blundell (born 1935). Mother of:

Henry Victor William Blundell-Hollinshead-Blundell (born 1967), older son. Father of:

Byran Vahram John Blundell-Hollinshead-Blundell (born 2005) son.


But it is always possible that heirs of Ingeborg of Werle (d.1509) and her husband Everwin II, Count of Bentheim might be traced, who would have superior claims to being the rightful heirs of Erik V, Erik VI, Christopher II, and Waldermar IV..

I want to know why the Dutch William III went to be the king of the British. What does he have to do with the British royal family, but he does not merge Britain and the Netherlands?

I want to know why the Dutch William III went to be the king of the British. What does he have to do with the British royal family, but he does not merge Britain and the Netherlands?
William III didn't merge the Netherlands with Britain because there was insufficient public desire among the leaders of those two countries for such a union. Also a dynastic union wouldn't work. The Netherlands were technically a republic that William's family members often got selected to lead. His family didn't become hereditary statdholders of the Netherlands until 1747. Furthermore, William III and his wife Mary II were childless from their marriage in 1677 to Mary's death in 1694.

William III was the son of William II of Orange and Princess Mary of England, sister of King James II & VII. William's wife Mary II was his first cousin, the daughter of King James II & VII who William and Mary usurped the throne from. Thus the children of William and Mary would have next in line to the throne after ex king Jame's son James. Marry had at least one miscarriage but no live children.

Thus William II's heir on the House of Orange side was Jan William Friso (1687-1711) who was a maternal first cousin one removed and a paternal third cousin once removed. Jan William Friso, who was only 15 and inexperienced when William III die din 1702, never got to be stadtholder, but his son did. And Jan William Friso had no known descent from any English or Scottish monarchs In recent generations. I have found that Jan William Friso was descended from King John who died in 1216, 495 years before, but I don't know if Jan William Friso had any later kings of England and Scotland in his ancestry.

Thus there were thousands of other persons who had better claims to the English and Scottish thrones than Jan William Friso who didn't have a very strong claim to be Stadtholder of the Netherlands anyway, so William III had no way to find someone who would be an acceptable ruler of both the Netherlands and the British Islands.

Heirs of the Union of Kalmar.

The Union of Kalmar was a personal union of the three kingdoms of Norway, Sweden, and Denmark created by the ambitious and powerful Queen Margaret I. It lasted for 126 years from 1397 to 1523. Actually due to various troubles, mostly in Sweden, the complete Union of Kalmar lasted on and off for only about 53 years out of those 126.

The list of monarchs of the Union of Kalmar is:

0. Margaret I, regent & otherwise de facto ruler 1397-1412.
1. Erik 1397-1439/42.
2. Christopher (1440-1448).
1. Christian I (1448-1481).
4. John (Hans) (1481-1513).
5. Christian II (1513-1523).

So the list of the heirs of Margaret, Erik of Pomerania, and Christopher are:

1. Duke Albrecht IV of Mecklenburg (d. 1387/88). The son of Queen Margaret's older sister Ingeborg. His first cousin Olaf was selected as King of Denmark in his place. Albrecht IV was childless. Brother of :

2. Euphemia of Mecklenburg (d. 1400). Married but childless. Sister of:

3. Marie of Mecklenburg (1363/67-1402). Sister. Married 1380 Duke Wartislaw VII of Pomerania. Mother of:

4 .Erik Bogdislaw (1381?-1459). Son. Duke of Pomerania. King of Norway 1389-1442. King of Denmark 1396-1439 and Sweden 1396-1439. Deposed. Since he outlived his nephew and heir, he was the last surviving descendant of Margaret and Ingeborg's father King Waldemar IV. Uncle of:

[Christoph (1416-1448) Sister's son. King Christoffer III of Denmark 1440-1448, King Christof of Sweden 1440-1448, King Christof of Norway 1441-1448. Childless.]

The nearest royal relatives of Margaret, ERik, and Christoper, were descendants of King Erik V "Kipping" (c.1249?-1286) of Denmark, the great grandfather of Margaret and her sister Ingeborg. His daughter Richiza (died 1303/08) married Lord Nicholas of Werle (d. 1316). Their daughter Sophie was the great great grandmother of King Christian I of Denmark, Sweden, and Norway, but their son Johann III of Werle (d. 1352) was the father of Nicholas IV of Werle (d.1354) the father of Johann IV of Werle (d. 1374) who died childless.

Lord Johann IV of Werle had two sisters. One, Mechtild (d. 1402) married Lorenz of Werle (d. 1393). Their first son Balthasar of Werle (d.1421) was childless. Their second son Johann VII of Werle (d.1417) was childless. Their third son Nikolaus of Werle (d.1401) was childless. Their fourth son Wilhelm of Werle (d. 1436) had a daughter Katarina (d. 1475/80).

5. Katarina of Werle (d. 1475/80) was the heiress of King Erik of Pomerania if her grandmother Mechtild was the older sister of Lord Johann IV of Werle. Katarina married Duke Ulrich II of Mecklenburg-Stargard (1438?-1471). Their daughter Elizabeth was a prioress and died childless. Their other daughter Ingeborg (d.1509) married Everwin II, Count of Bentheim. Apparently there were two counts Everwin II of different Bentheim branches at the same time, so I will not try to trace Ingeborg's descendants now.

6. Ingeborg (d. 1509) possibly the older daughter of Katarina of Werle and thus the heiress of Denmark.

Until Bentheim descendants are traced the only known descendants of Richiza of Denmark and Lord Nikolaus of Werle are thrrough their daughter Sophie (d.1339), who married Gerhard III Count of Holstein-Schauenbuerg (d.1340). Gerhard and Sophie had a oldest son Henry II Count of Holstein-Rendsburg (1317?- 1389) who had an oldest son Gerhard VI of Holstein-Rendsburg (d. 1404) who became Duke of Schleswig in 1386. Duke Gerhard of Schleswig had sons Duke Heinrich IV of Schelswig (1397-1427), and Duke Adolf XI of Schleswig (1401-1459), who were childless, and Duke Gerhard (1404-1433), who had twins born in 1433. The boy twin Heinrich drowned mysteriously and his sister was a nun. Duke Adolf XI had a sister Hedwig (1398-1436) whose first marriage had no children and married secondly Count Dietrich of Oldenburg (d, 1440) and their oldest son became King Christian I of Denmark and Norway. King Christian I (1426-1481) was the father of:

7. King Johann I of Denmark, Norway, and Sweden (1455-1513). He became the rightful heir of Denmark in 1509 when Ingeborg of Mecklenburg-Stargard died, unless she left Bentheim descendants. Father of:

8. King Christian II of Denmark, Norway, and Sweden (1481-1559) Deposed in 1523. Father of:

9. Dorothea of Denmark (1520-1580) married Frederick II (1482-1556) elector Palatine. No Children. Sister of:

9. Christina of Denmark (1521-1590). Sister. Married first: Duke Francesco II of Milan. No Children. Married second: Duke Francis I of Lorraine (1517-1545). Mother of:

10. Duke Charles III of Lorraine (1543-1608), father of:

11. Duke Henry II of Lorraine (1563-1624). Father of:

12. Nicole (1608-1657) rightful Duchess of Lorraine. Married her first cousin Duke Charles IV of Lorraine. Childless. Aunt of:

13. Ferdinand Philippe (1639-1659). Son of [Claude (1612-1648), sister of Nicole. Married her first cousin Duke Nicolas Francis of Lorraine.] Childless. Brother of:

14. Duke Charles V of Lorraine (1643-1690). Father of:

15. Duke Leopold Joseph of Lorraine (1679-1729). Father of:

16. Emperor of the Romans Francis I Stephen (1708-1765). Father of:

17. Joseph II Emperor of the Romans (1741-1790). No surviving children. Brother of:

18. Emperor of the Romans Leopold II (1747-1792) father of:

19. Emperor Francis II & I (1768-1835) Father of:

20. Ferdinand I, (1793-1875), Emperor of Austria 1835-1848. Childless. Brother of:

21. Archduke Karl Franz(1802-1878). Renounced his rights to Austria in 1848. Father of:

22. Emperor of Austria Franz Joseph (1830-1916). Grandfather of:

23. Archduchess Elizabeth (1883-1963), daughter of Crown Prince Rudolf (1858-1889). Married first Prince Otto Wieriand of Windisch-Graetz. Mother of:

24. Franz Joseph Prince of Windisch-Graetz (1904-1981). Oldest Son. Father of:

25. Guillaume Prince of Windsch-Graetz (born 1950). Born 1950. Unmarried. Brother of:

Stephanie (born 1939). Sister. Married Dermott Hugh Blundell-Hollinshead-Blundell (born 1935). Mother of:

Henry Victor William Blundell-Hollinshead-Blundell (born 1967), older son. Father of:

Byran Vahram John Blundell-Hollinshead-Blundell (born 2005) son.

This is assuming that the rightful heir of number 28 Emperor Franz Joseph (1830-1916) would be his granddaughter Elizabeth though male preference primogeniture allowing inheritance by daughters when their are no sons to inherit. If the habsburg-Lorraine claim to the Union of Kalmar passes through agnatic (male only) primogeniture, the heirs of number 28 Emperor Franz Joseph would be:

23. Maximilian, Duke of Hohenberg (1902-1962) the older son of Archduke Franz Ferdinand (1863-1914), who was the older son of Archduke Karl Ludwig (1833-1896), a brother of number 28 Emperor Franz Joseph. Father of:

24. Franz, Duke of Hohenberg (1927-1977). Had two daughters but no sons. Brother of:

25. George Duke of Hohenberg (born 1929). Father of:

Prince Nikolaus of Hohenberg (born 1961). father of:

Prince Karl of Hohenberg (born 1991).

According to the dynastic laws of the Habsburg-Lorraine dynasty, the throne could pass only to children of equal marriages with persons of high rank, which made the dynastic heir of number 28 Emperor Franz Joseph:

23. Emperor of Austria Charles I (1887-1922), son of Archduke Otto Franz (1865-1906), younger son of Archduke Karl Ludwig (1833-1896), a brother of number 28 Emperor Franz Joseph. Father of:

24. Crown Prince Otto (1912-2011). Father of:

25. Karl von Habsburg (born 1961). Father of:

Ferdinand Zivonimir von Habsburg (born 1997).

There is another possible Way to trace the heirs of Margaret, Erik, and Christopher. When Christopher died without children in 1448 his successor Count Christian of Oldenburg, who became King Christian I, married Dorothea of Brandenburg (1430/31-1495), the Widow of King Christopher. Thus there was a genealogical connection between King Christopher and his successor King Christian I, even though King Christopher had no children or other descendants or siblings. Thus one could list the heirs as:

5: King Christian I (14261481). Father of:

6: King Johann I of Denmark, Norway, and Sweden (1455-1513). And he is the same as number 7 on the list above, so to trace this line of heirs just copy the line above from number 7 onward and reduce each number by one.

But it is always possible that heirs of Ingeborg of Werle (d.1509) and her husband Everwin II, Count of Bentheim might be traced, who would have superior claims to being the rightful heirs of Margaret, Erick, and Christopher of the Union of Kalmar.

So who are the heirs of the next three monarchs of the Union of Kalmar, Christian I, John, and Christian II?

King Christian I of Denmark, Norway and Sweden (1426-1481). Father of:

King Johann I (John, Hans) of Denmark, Norway, and Sweden (1455-1513). Father of:

King Christian II of Denmark, Norway, and Sweden (1481-1559) Deposed in 1523.

Note that King Johann I (John, Hans) of Denmark, Norway, and Sweden (1455-1513) is the same person as number 7. on the first list above, and that his son King Christian II is the same person as number 8 King Christian II in the list above. So King Chrisitan II's daughter and heiress Dorothea is the same person as number 9 on the first list above. So this list is the same as the first above list, except that that everyon'ee number needs to be reduced by 8. Thus the three possible heirs are number 17 instead of number 25.

So until and unless a heir of Ingeborg of Werle (d.1509) and her husband Everwin II, Count of Bentheim can be traced, the three potential heirs of Emperor Franz Joseph are the three potential heirs of the kings of the Union of Kalmar from 1397-1523.

Heirs of the first three kings of the Union of Kalmar. Continued from Post # 6.

Post number 6 begins quite abruptly with Katarina of Werle (d. 1475/80) nearest cousin of King Erik of Pomerania. Married Duke Ulrich II of Mecklenburg-Stargard (1438?-1471). I had to shorten it to fit in the length limit. Here is the justification for making Katarina of Werle the heir of King Erik of Pomerania.

The first ruler of the Union of Kalmar was Margaret (1353-1412), who ruled in the name of her selected heir, Erik of Pomerania, who she made king of Denmark, Norway, and Sweden. Margaret selected Erik from her relatives descended from Danish kings, not the relatives of her husband King Haakon of Norway and Sweden.

Margaret was the daughter of King Valdemar IV "Atterdag" of Denmark. Her only child, King Olaf II of Denmark and IV of Norway, who was also the more or less rightful king of Sweden, died childless in 1387. Margaret's only sibling to have children was Ingeborg (1347-70), who married Duke Heinrich (Henry) of Mecklenburg. DENMARK KINGS

Ingeborg and Henry had a son Albrecht who died childless in 1387/88. Since his mother was older than Margaret, by genealogy Albrecht (died 1387/88) should have been King of Denmark instead of Olaf while Olaf should have been King of of Sweden instead of Albrecht of Mecklenburg (d. 1412) who was next in line after Olaf and an uncle of Albrecht (died 1387/88). MECKLENBURG

Next in line after Albrecht - the one who died in 1387 or 1388 and not the one who died in 1412 - were his sisters. Euphemia (d. 1400) married in 1377 Johann V Prince of Werle-Gustrow but didn't have any children. MECKLENBURG

The youngest sister Ingeburg (1368-1408) became a nun in 1377 and didn't have any children. The other sister Marie (1363/67-1402) married Wartislaw VII Duke of Pomerania. MECKLENBURG

Marie and Wartislaw had two children, Erik (1381?-1459) and Katarina (1390?-1426). After King Olaf died in 1387 Margaret passed over Albrecht (d.1387/88) if he was still alive, and Albrecht's sisters Euphemia, Marie, and Ingeburg, and adopted Erik and Katarina as her heirs. POMERANIA

Margaret made Erik King of Norway in 1389 and king of Denmark and Sweden in 1396, but he was deposed in 1439. Katarina married Johann Count Palatine of Neumarkt (1983?-1443). POMERANIA They had five children who died young and Christoph (1416-1448, who became King Christopher of Denmark, Sweden, and Norway in 1440 but died without any children. That left the childless ex king Erik as the last surviving descendant of King Valdemar IV "Atterdag" of Denmark, and Erik died in 1459.

King Valdemar IV "Atterdag" of Denmark (1320?-75) was a son of King Christopher II of Denmark (1276-1332). Christopher's daughter Margaret (1305?-40) married Ludwig V of Bavaria, Elector of Brandenburg (1316-61) and had a son Matthias who seems to have died young. BAVARIA DUKES None of Christopher's other legitimate children are known to have had children. Christopher's brother King Erik VI "Maendved" (1274-1319) had no surviving children. Their sister Margaret married King Birger of Sweden but they don't seem to have had any grandchildren. SWEDEN KINGS The other married sister of King Erik VI and King Christopher II, Richiza (d. 1303/08), married Nikolaus II Lord of Werle Parchim . DENMARK KINGS

The lords of Werle were a branch of the dynasty of the Dukes of Mecklenburg. Richiza (d. 1303/08) and Nikolaus II of Werle Parchim (d. 1316) had a daughter Sophie who was an ancestor of King Christian I of Denmark, Norway, and Sweden. But they also had a son Johann III of Werle (d. 1352), father of Nikolaus IV of Werle (d. 1354) who had a son Johann IV of Werle who died childless in 1374. Johann IV of Werle had two sisters who married, Mechtild (d. 1402) and Agnes (d. 1383). MECKLENBURG

Agnes (d. 1383) married Johann VI of Werle (d.1389/95) and had a son Nikolaus V (d. 1408) who had a daughter Jutta of Werle (d. before 1427) who married Duke Heinrich (Henry) of Mecklenburg-Stargard (d.1466) as his first wife. They had no children, but Duke Henry had a son Duke Ulrich II (1428?-1477) by his second wife Ingeborg of Pomerania. MECKLENBURG MECKLENBURG MECKLENBURG

Mechtild (d. 1402) Married Lord Lorenz of Werle (d. 1393) and had three childless sons, Balthasar, Johann VII, and Nikolaus, and a son Wilhelm (d. 1436) who had a daughter Katharina of Werle (d.1475/80) who married Duke Ulrich II (1428?-1477) of Mecklenburg-Stargard. MECKLENBURG MECKLENBURG Their daughter Elizabeth (died 1532) was a prioress and thus childless. Their other daughter Ingeborg (d. 1509) married Count Everwin II of Bentheim (d. 1530).

And post # 6 traced the heirs of Ingeborg (d. 1509) and Count Everwin II of Bentheim (d. 1530). And all of the above is necessary to explain and prove the statement that Katharina of Werle (d. 1475/80) was the rightful heir of ex King Erik of Norway, Sweden, and Denmark who died in 1459.

The heirs of King Valdemar I the Great of Denmark.

With the reign of King Valdemar I the Great of Denmark the Kingdom of Denmark began to pass (with some exceptions) from father to son, instead of being up for grabs by any member of the royal family who could grab it and hold it.

Byran Vahram John Blundell-Hollinshead-Blundell (born 2005) son.

Since the claim to be heirs of King Valdemar I passed by male preference primogeniture to the house of Habsburg-Lorraine I assume it should be inherited From Franz Joseph that way. The heirs by agnatic (male only) primogeniture of the claim of Emperor Franz Joseph to be the heirs of King Valdemar I are:

29. Maximilian, Duke of Hohenberg (1902-1962) the older son of Archduke Franz Ferdinand (1863-1914), who was the older son of Archduke Karl Ludwig (1833-1896), a brother of number 28 Emperor Franz Joseph. Father of:

31. George Duke of Hohenberg (born 1929). Father of:

Prince Nikolaus of Hohenberg (born 1961). father of:

Prince Karl of Hohenberg (born 1991).

According to the dynastic laws of the Habsburg-Lorraine dynasty, the throne could pass only to children of equal marriages with persons of high rank, which made the dynastic heirs of number 28 Emperor Franz Joseph:

29. Emperor of Austria Charles I (1887-1922), son of Archduke Otto Franz (1865-1906), younger son of Archduke Karl Ludwig (1833-1896), a brother of number 28 Emperor Franz Joseph. Father of:

30. Crown Prince Otto (1912-2011). Father of:

31. Karl von Habsburg (born 1961). Father of:

Ferdinand Zivonimir von Habsburg (born 1997).

Heirs of King Valdemar I the Great of Denmark Part Two.

In post number 8 above I traced the heirs of King Valdemar I the Great of Denmark (1131-1182), reigned 1154-82 down to Sophie (d. 1286) who married King Valdemar of Sweden (1237-1302), reigned 1250-1275). And I traced the heirs of King Valdemar of Sweden's daughter Ingeborg down to Emperor of Austria Franz Joseph (1830-1916). And Emperor Franz Joseph's three possible heirs are Guillaume Prince of Windsch-Graetz (born 1950), George Duke of Hohenberg (born 1929), and Karl von Habsburg (born 1961).

But King Valdemar of Sweden had two other daughters who married, and either of them might possibly be the older daughter and heiress.

Rikissa (d. 1288/93), another daughter of King Valdemar of Sweden, married Duke Przemysl of Great Poland (1257-1296) who reigned as King Przemysl II of Poland from 1295-1296 POLAND. Mother of:

Ryksa Elzbieta (1288-1335) was the second wife of King Wenceslaus II of Bohemia BOHEMIA. Mother of:

Agnes (1305-1337) who married Heinrich I, Duke of Jauer, but had no children. SILESIA

Marianna, another daughter of King Valdemar of Sweden, married Rudolf of Diepholz (d. 1303 or later) without recorded children. http://fmg.ac/Projects/MedLands/SAXON NOBILITY.htm#RudolfDiepholzdied1303 Rudolf was childless and a great grand uncle of Johann of Diepholz (d.1421) who married Kunigunde of Oldenburg and was the great grandfather of 13. Rudolf VIII Noble Lord of Diepholz (reigned 1484-1510) the first Count of Diepholz in post number 8 above..

The other daughters of King Valdemar of Sweden never married. So unless there are any traceable legitimate present descendants of Erik Valdemarsson (1271/72-1330), or unless there are any traceable legitimate present descendants of Anna of Oldenburg (d.1438) and Count Otto III of Waldeck (d. 1458/590, or unless there are any traceable legitimate present descendants of the lords and counts of Diepholz descended from Kunigunde of Oldenburg the wife of Johann of Diepholz (d. 1421), there are only three potential genealogical heirs of King Valdemar I the Great of Denmark though King Valdemar of Sweden, Guillaume Prince of Windsch-Graetz (born 1950), George Duke of Hohenberg (born 1929), and Karl von Habsburg (born 1961).

The Heirs of King Erik IV "Plow Penny" of Denmark.

King Erik IV (1216-50) had no surviving sons when he was murdered in 1250, so his brother Abel was the next king. King Erik IV's daughter Sophie (d. 1286) who married King Valdemar of Sweden, was assumed to be his oldest daughter in post number 8 and post number 9 above. But if Sophie's sister Ingeborg was older than her the succession would be:

1. Ingeborg (1244?-12887) married King Magnus IV of Norway.(1238-80). He is the fourth heir in post # 4, Heirs of King Sverre of Norway, in the thread Heirs of the kingdom of Norway. Heirs of the Kingdom of Norway So we can just copy and renumber the heirs from that post to get:

This marriage is considered unlikely to have happened, and no children are recorded. DENMARK KINGS - SCHLESWIG-HOLSTEIN.

So if Ingeborg was the older daughter King Erik IV of Denmark, his heir would be the heir of the Dukes of Mecklenburg, either Donata of Mecklenburg-Schwerin (born 1956) or her 7th cousin once removed, Duke Borwin (born 1956) of Mecklenburg-Strelitz. And if Sophie was the older daughter King Erik IV of Denmark, his heir would be the heir of Emperor of Austria Franz Joseph (1830-1916), whose three possible heirs are Guillaume Prince of Windsch-Graetz (born 1950), George Duke of Hohenberg (born 1929), and Karl von Habsburg (born 1961).
