Interesting to see that very little is known about the Gaona surname. I've been trying to gather information about my family line of Gaona, but with no luck. From my understanding, my great grandfather brought his family (his wife / my great grandmother and two children - my grandfather and his sister) to San Marcos, Texas from Monterrey, Mexico in the early 1900's. Nothing is known about my great grandfather's life in Mexico. We understand that my greatgrand father had no siblings (that we are aware of). If you have any knowledge of a Bartolo Gaona or you have relatives that are Gaona in/from Monterrey, Mexico, I would love to hear from you. Thanks.
