My Uncle was also named Angel Alfonso Garayua. I believe he fought on the American side in World War II. He lived in Yonkers in the 1970's. I do not know who his children are because he always came to visit my mother, his little sister, by himself in Ponce, Puerto Rico. His only brother was Miguel Garayua, also of Ponce, Puerto Rico who died in 1968 or 1969.
