My grandfather, Marcial Ramirez, bord 1890 from Guanajuato, migrated to Northern CA to work in the fields during 1930's-1940's??Met someone and had a son, went back to Mexico shortly after.Was married to Eleuteria and had several children including my dad Gabriel Ramirez, born 1946.Heard a story that about 20? yrs after my grandfathers return to Guanajuato, a young man went serching for him claiming to be his son. My dads older sisters basically denied any relation and sent him away. My father is now 65 yrs old I'm estimating this person to be about 80-85yrs of age. Any info would be greatly appreciated.
