I have no information on Luis Gauna other than that he was a cousin of my grandfather Robert Sanchez Padilla. He is a possible brother to Martin Gauna. This was taken in WWII. I do not know what branch of the service he was in, but I'm guessing it was the Army. This comes from the collection of my great uncle Raul Sanchez Padilla. I am attempting to research his family tree also, but again, I have no other information available on him that the above which isn't much.
