I am not sure if i can help but i do know how fustrating it could get not to get answers.
The
Alvarez in my family is Raphel
Alvarez which would be my grandfather. He and my grandmother, Casimira Ynigo had a daughter (my mother rebecca alvarez) Raphel and Casimira did not stay together, Casimira moved to mexico and i don't know where Raphel went. They were both living in
Marana,Az. probably before my mother was born in 1929 and maybe a while after.
