Very interesting. My great grandmother is a Maria Zuniga born in Zacatecas, her father was of French Mediterranean origin. He was born in south eastern France. He came to Mexico for unknown reason (many stories) and ended up just moving place to place until he settled down in Zacatecas. I know his parents followed him for a while until when he made a stop at Jalisco for a year or so but then they returned to France.
