Hi Frances,
Any more information on the Cardona side? Both my grandparents were born in Aguascalientes, as was my first aunt. Although they had moved from Aguas by 1910, I'm sure they still had family there. I assume your husband's mother's last name was Macias? If so, what was here husband's first name? I'll bet there's a connection to my family.
Good luck in your search,
Denny
