I was just surfing this genealogy forum and saw your message.
Believe it or not I am a "Balles" and my grandfather is from Mexico but somewhere along the line when my grandfather crossed over his name was changed.Supposedly the real family name is 'BAIZ'.I have never been able to figure that out because how could he (my g/f)have been given a alien regisration card under BALLES, social security number etc. etc.??? Anyway, his children, among them my dad,runs under BALLES. I plan to request my g/f's social security record to see how he spelled out his father's name.Need to figure out what happened there.
