My father was born in Tenamaxtlan, Jalisco, Mexico to Pedro Padilla. In my father's birth certificate his father is listed as a mestizo, suggesting my grandfather was mixed with European(probably Spanish) descent as well as indigenous blood. Limited research has found the Padilla name to be linked to Spaniard Basques in Spain. Anyone have a related story or additional information that might help?
