descendants of Gjergj Kastrioti Skanderbeu

Voltaire claimed that Skanderbeu's Albanian revolt against the Ottomans had saved Italy and Western Europe.

He has descendants in Italy, whose male lines are fairly easy to chart (which I have done) but whose female lines need much more expertise in Italian noble families than I possess. Through a grand-daughter he also has descendants in the Austro-Hungarian, Belgian, Luxembourg, Prussian, and Serbian ruling (or ex-ruling) families, plus a couple of members of the British royal family.
