sevaral sites suggest that premier Kung Hsiang-hsi (1881-1967) was among confucius' descendants

from whom in the sage's main line did his family branch off from?

what is his lineage from that point? corollary, how many generations is he from the point his family broke off from the main line?

thank-you
