I don't know if you are still researching the Jemery name, but I just found out something that might interest you. My mother's grandmother was Emma Jemery. Her father was Napolean and his father was John Jemery and wife was Julia. Anyway, I have had trouble also finding out info from Canada. Interestingly enough, it turns out that John Jemery was born in Canada about 1809 (Quebec). When he came to the states, he was known as John Jemery or Jean Marie, but in Canada he was John Baptiste Hogue dit Jean Marie. His father was Jean Marie Hogue. Hope this helps! I was able to trace the Jemery/Hogue name back to France with this information!
