I don't really know much about the history of Pakistan and Afghanistan Shaheen.
The article does mention King Abdur Rahman. Wikipedia says he was the Emir of Afghanistan from 1880-1901 ...
I am aware about the Kalash people. According to some sources they are the leftovers of the forces of Alexander as they are pretty White and some have light hair as well.
One of the articles I read about Pashai people stated that they might have been forced to move North by the Southern Pashto speakers in the past.
What makes you think that the Hindkowan and the Potohari may have links with the Gandharan people. We have many examples of newcomers living in lands which belonged to different people in the past.
