My Grand-Father Salvador Nunez was a Capitan in the Mexican Army and fought along side Pancho Villa. I don't know the years my Grand-Father served, I thought that by looking for records may give me the information I'm looking for. He came from Spain and my understanding is that the minute he sat foot on Mexican soil he was made Mexican citizen and drafted to serve. Does anyone know where I could find such records? Any information will be appreciated. Thank you.
