His middle name is his mother's name. She was Juliana Perales who married Vincente Gaona or as some records show Jose Bicente Gaona (spelled GAUNA in the record), married at San Nicholas, Ramos, Arizpe, Coahuila, MX. I have found 5 other children than Pedro. Go to Family Search dot org. I have been working on this tree for "Bobby" Gaona for his birthday.
