Hi Marilyn, What about land records and wills in St. Lawrence County? The census also tells where they lived and who their neighbours were, which can also help find relatives in the area. I left 2 postings on Ancestry for you asking for information from 2 other researchers who had Francis and Delia in their trees. I think it would be good for you to "flesh out" the family tree of Etienne Desrosiers and Marie Madeleine Caty. By that I mean hook up with the folks working on that line. As Etienne was born in Mille Roches, someone will have more for you. There are lines listed on the Corwallgenes page. By connecting with "cousins" you may find that someone has a little scrap of information that you need. The big problem that you may have is that Desrosier was used as a dit name in combination with other surnames. You will see at least 5 combinations on the Cornwall site, so you may need to look at some of those names in the Mille Roche area, too. Mary Frego Coates
