One of my grandparents was an orphan, so on one side, the paper-trail ends there. On my mother's side of the family, we go back to the 14th century french nobility, so I'm not sure how I should look at it, since back-then - the country where I currently live (Belgium) didn't even exist. So - very tricky question!
