... is Jean-Baptiste Vésinat (1718-) a 1st cousin 8x removed, from L'Ange-Gardien.
He's the son of Pierre Vésinat (no blood relation - at least so far), and 7th great-grand aunt Jean LeTartre (1683-1765), the daughter of 8th great-grandfather Charles LeTartre.
This is family #18 in the current project of mapping all the 1st cousins X times removed (i.e., C:X,2's), out of 196. I'm clearing about one family a week (some take much longer, if there's a lot of cousins who get married).
Still hoping for a trip to Québec in early 2016.
