Hello,
I have a Palacio in my family history, so thought I would put this out there.
My GGrandmother's maiden name was Palacio, first name Petra.
Originally from Zacatecas. Born in late 1870's. She married into Zamarripa family in late 1890's.
Lived in Aguascalientes/RIncon de Romos before moving to Los Angeles in the early 1920s, with her daughter Juana's family.
She had a son and two daughters, Juana and Consuela (Nini). I can't remember the son's name, as he died in the 1930's, well before I was born.
The family, minus my GGrandfather Zamarripa (who never returned from the war-revolution) moved to Los Angeles circa 1922.
