I have been recently researching my wife's Banlier family. We have been working in online records from the city of Poitiers in recent months on one of her other lines. The best I can figure out so far is that there are no records of Banlier family members there. We are still looking. There are, however, quite a few in the nearby state to the west of Deux-Sevres. There is a ton of information on perish records from that time but it is all scanned old parish record books, and is very arduous looking through ech record. So, possible progress here, but not yet a breakthrough.
