I don't know any more information, but my Grandmother Betty Rita Delgado b. 1927 Los Angeles, CA, and her mother was Louise Mary Degado AKA Louise Mary Amador b. abt 1900 in Los Angeles.
Louise had about five other siblings; Manuel, Lupe, Jenny [possibly Juanita], John [Juan ?] and Antonio Delgado of Los Angeles.
Their Grandmother was Fermina Caldar born in Zacatecas married Louis Delgado.Fermina's mother was Feliciana Caldar [it's hard to make out the name but it almost looks like Cald e r o n, but I'm not sure]
