Mondon Family Genealogy Forum
I have been trying to trace a Peter Monden family fron Ontario who came into MI after 1870, but not too much after. They settled up in the Bay City area as far as I know.
Peter Monden is on the city directory for Bay City in 1908 with a few children.
Sorry they do not match your family names, but at this point I don't know for sure any of the childrens names.
There I other Mondens in the Detroit area on the census (might even be a Peter) so try other spellings such as Monden.
