If the James F. Hill in post #2 is correct, I found the following. (How do we know that's the right one? The link has no info except for name.)
He was born in Boston April 21, 1921 to James F. Hill and Anna B. Benson. James Sr, his father, was born in 1893 in Crane, MO, to James Hill and Louise Young and married Anna on 21 April 1918 in Ayer, Massachusetts,, when she was 19. The wedding was performed by the chaplain at Camp Devens, so he was probably in the service at the time. He was living in Shelby, Idaho, when he went into the service. He was a blacksmith and she was a weaver. Her parents were William F. and Josephine F. Horne (or Howe, the handwriting is hard to read).
James Sr died in 1949 and is buried in Framingham, Mass. Anna died in 1984. Before James, they had a daughter, Marion Zetta Hill (Brooks), who died in 2003.
Marion and her husband Morton had 3 children: Sandra, Douglas, and Linda, who would be the nieces and nephews of James Jr. Sadly, Linda died just last month. Her obituary lists the survivors, who could be tracked down to verify if this is the right James F. Hill Jr and if they want to claim him.
