Rhiannon, thanks for your reply and your patience waiting for mine. (I don't go on line much these days.) I'm interested in a couple of things in your post. First, where did you find/hear the information about the Deneau who married the Indian woman? What is White Cloud's tribe? Approximate date/location for this marriage? These types of inforamtion could be helpful for any of us looking to connect up names, especially since many times people went by more than one name - and very often a native name is replaced by a French name in marriage records. So it'sn possible we could have information on this marriage and not realize it's the same one.
Also, about the Belisle/Belche - that's intriguing. The Belisle family name in my line appears to be a "dit" name, for the name Germain. Belisle is also sometimes spelled Belleisle (possible Belle Isle?) Thant Germain family is a French family, and the name is alleged to mean "Cousin". It's possible that your family story is mixed up about the German ancestry because of the similar word Germain. Or, perhaps the original name may have been a different German name entirely. What do you think? Very interesting.
I second that statement about prejudice (or fear and our ancestor's need to survive) creating a lot of blank spots and discrepancies in the family stories and records. It makes it very difficult.
Any info you have about the Deneau native connection, AND about the NW Fur Trading Co connection will be so much appreciated. you can send this to me via e-mail at firstname.lastname@example.org
If you contact me there, I will also try to find a genealogy sent to me by another researcher and forward it to you. You may find some more relatives! Good wishes,
