Fred C. Trump Jr.
From RAGEPATH Wiki
Freddy left real estate to pursue his passion for flying, working for Trans World Airlines, which gave him some good years. In 1962, at age 23, he married Linda Clapp, a stewardess. They had two children, whom they named Fred and Mary, after Freddy's parents. The family settled in Queens and spent free time with Freddy's childhood best friend, William Drake, also a pilot, and his wife, Ms. Schifano. [...] But as he reached his mid-20s, he began drinking heavily. [...] The years that followed were unkind. He got divorced, quit flying because he knew his drinking presented a danger and failed at commercial fishing in Florida. By the late 1970s, he was living back in his parents' house in Jamaica Estates, working on one of his father's maintenance crews. (New York Times, January 3, 2016)”
