A BALKAN ANCESTOR?
“You most likely had a third-great-grandparent, fourth-great-grandparent, fifth-great-grandparent, sixth-great-grandparent, or seventh-great- (or greater) grandparent who was 100% Balkan. This person was likely born between 1700 and 1820.”
Hmm. I wonder who this is. I should study the family tree more carefully, hunting for locations in the Balkans. Perhaps somewhere in the Austro-Hungarian Empire?
