My dad's step-mother's daughter Margarita Dorado married a Manuel Alderete. I'm not sure where Margarita was born but her mom Maria Cruz Dorado married my grandpa in the 1920's in the city of Zacatecas.
Margarita was Maria Cruz Dorado's daugher from a previous marriage. Margarita and Manuel children were Manuel, Guadalupe, Pedro and Socorro. Manuel Jr., was born in U.S. the couple went back to Zacatecas, the story was that Manuel was well off, and Margarita was always well dress. The couple lived in U.S. it is believe that Manuel Sr., was born in U.S.
