I do not understand, as your first message said Joseph M* m Agnes Rheault, andI found that Francois was Joseph's father in Remi M*'s marriage book?? One of the children of Joseph & Agnes was Felix-Omer, who married Josephine-Louise St-Louis on 4 sept 1890 at St-Joseph KS. They had at least 2 sons, one named Felix Omer who married in 1931 to Unknown in Las Vegas NV, and one named Silver-S who m Rose-Alba Sarazin 2 sept 1914 in LA CA.
And there, the line ends. But this sure sounds like what you are after to me. You might contact Remi directly, and see if he has any later data on this line. I know he is still working on it, as he informed me a few days ago that he is planning on doing another issue soon.
