Thank you again Annie. I was pretty certain that Genevieve was born in Ontario, but I needed the Alberta Census to help verify this. I think that Charles Froats was not able to easily obtain a birth record, and that is why Myron did the Declaration of Birth for him at the time. My paternal grandfather (married to Genevieve), also named Charles, needed a birth certificate also (I think for Social Security purposes, as in was done in the 1940s), and his father, Damian Fox, did a late filing affidavit for him. In my grandfather case, I think that there is an actual birth record available, but my grandfather was trying to hide part of his past, and so had the birth recorded as taking place in a different county. Sometimes it was easier to establish a new birth record than try and retrieve a copy of the original.
Unrelated to this forum, I am trying to get an official copy of my maternal grandmother's birth record, which is in Mexico. This one is going to take some time, as I need to correspond with the current Catholic Church authorities (in Spanish) to make the request. This record will actually be used to re-establish my family's Mexican nationality (I have family roots across this border also), as the laws in Mexico now will allow this to be done.
