For Lt. Col. Dominic R. Baragona, the military was his career, but his family was his life. He especially liked Christmas and always made a big deal of getting the family together, said his father, Dominic Baragona of St. George Island, Fla. “Every Christmas he was the guy who put it all together,” his father said. “He was the one who spent the most on Christmas presents. That was his style.”
