I have been working on my family tree and have hit a roadblock. Apparently our surname used to be Lepine until one of Francois Lepine's descendants changed it to Mathieu, I believe it was Ambroise Lepine who did this. However the furthest I can go back is to Francois Lepine and Angelique Hardy around 1800. Mathieu Lepine, who was Francois son is shown as living in Louisiana in 1812. Any information any one can give me on this would be greatly appreciated.
