I am looking for information on the name Roullier, from what I was told Twin River(s), Canada, and later settled in NY, with ties to the Seneca tribe. From what I was told the Roullier name ties my genealogy back to Seneca. However, I don't have a name. The only name I have is Singuor Roullier, who would have came later, at least in my tree. Thanks for your help.
