I do not know if perhaps we search for the same person. My great grandmother was Sofia Mendez Diaz Santillan.They were married sometime around 1919. My grandmother was born in Kansas in 1921,my great-uncle in 1924. Supposedly, he abandoned her, although they were married,sometime in late 1923/early 1924. In October of that year, she remarried.The name on my grandmother's birth certificate is actually Herculano Santillan, and he was 43 years old.However, since he was a labourer of some kind, (he may have worked for the railroad)it may have been a name given to indicate his strength. I do not know that these are the same person but I was curious about his family.
