My dad is Jesus Grimaldo. His mother (my grandmother) Gregoria Ruiz from Cerritos, San Luis Potosi. She was married to Albert (or Robert) Grimaldo. She divorced or separated from him after my dad was born, he had another wife and family in a nearby town, northeast of San Luis, the capital. I never knew my grandfather, but what my aunt told us was that he went to Chicago with his other family; my dad's half brothers and sisters may still be there, but my grandfather returned to Mexico before he died. I don't know where he is from orginally. We travel to Cerritos frequently because my grandmother's house is there and some family. My dad and I grew up in Harlingen, TX. It would be nice to hear from any family in Chicago. My grandfather had three children with my grandmother: Lupita, Maria Pilar & Jesus.
