There only appears to be 1 man, born David John Wesley Trump. But he married in 1911 as David John Wesley Tromp, and joined the army as John Tromp, later changed to John Trump, later to David John Wesley Trump. He married in 1920 as David John Wesley Trump. I cannot find a divorce from his first wife. The first wife had another child called Tromp in 1924, I do know know who the father of that was. There was at least 1 child, in 1922, by the second wife, who died in 1923.
