Hi Bruce, I am very interested in this line as I think this is my ggggrandfather.You have listed a Bertha Tessier, b. May 7, 1892. I believe this is my grandmother as the birthdate is the same. My Uncle gathered some info several years ago, and some of it matches yours. I don't know how accurate his info is. I believe Bertha was the daughter of Christine Tessier and Albert Davis. Christine was the daughter of Adelaide Causley and Theophile (or Theodore Tessier). I believe my grandmother was living with her grandparents, which would be why she is listed on the census. Could you possibly send more info to me. My family wasn't very talkative about family history.
