Amateur genealogist from France, working mainly on his own family from France (Aude, Mayenne, North) but also from Belgium and Poland. I also have polish relatives who travel to US (Stoch, Gorecki/Gorecka).
I'm a french genealogist. And, if I already have a personnal website with my data that I intend to maintain, I think open and free collaborative family trees are a necessary complementary approach. Thus I volunteer to help growing the wikitree database.
