Hello. I am researching my wife's family tree. The person I am currently researching is her g-g-grandfather, José RUVALCABA. He would probably have been born around the 1890s.We believe he may have been from Aguascalientes, but we're not sure.He married(?) Manuela RODRIGUEZ, and had at least one daughter, Gertrudes, my wife's g-grandmother.For some reason, however, she went by the last name RODRIGUEZ, or so it is believed. (Maybe her parents weren't married?) At any rate, any help you can give is greatly appreciated. Thanks.
