Ancestry now has a record of my paternal grandparents’ marriage in Yuma, Pinal County, 1958. I was surprised by this because I always assumed they met and married in Texas and because my grandmother was 16 years old (!) when she married my mysterious grandfather. Remember, he shed his name when he came to the United States and Amelia lent him a name from her family tree. I wonder why they went all the way to Yuma to get married? They lived in Mesa at the time.
One of the witnesses was Maria Rangel, I think that was her mother who appears on the 1940 census in Cameron County, Texas, right outside of San Benito. The other witness was someone named Federico Partida who I was able to find on the same 1940 census of Cameron County, Texas, right outside of San Benito. Interesting.
