Very cool. My brother is the family historian, he has traced my family back to the 1400s. It seems my great great grandmother was from Russia, but we are having a hard time finding any information about her. It would appear highly likely that she was actually from White Russia- Belarus--but it's just unknown. The problem is that we don't have an exact spelling for her last name.
What we DO know, is that (I can't recall now) either her father or her husband drove the carriage when the Czar visited their city. Pretty sure it was her father.
It's amazing, my mom's side is fairly easily traceable, we have traced it back to the early 1700s in Italy, which is when they started keeping records, and on her other side, we've traced it back to the early 1800s. My dad's side though is much tougher. One side has been traced back to the 1400s, while the other side, we can't even trace back to the start of the 1900s!
