Casas family from Jerez, Zac.

Hello Manuel,
I am just now catching up with the NR digests and see you are researching Casas in Jerez.
My mother, Catalina Casas, the youngest of 12 children, was born in Guadalupe to Antonio Casas & Modesta Aguilar. Her birth date was 1917 so I'm guessing Antonio was born in the 1870's. I have not been researching the Casas name yet but thought your family and mine might be related since there were so many siblings.
