I'm curious about John Jacob Astor V, son of Madeleine and J.J. Astor. Did he ever give an interview with the press where he mentions the Titanic?
Would have been John Jacob VI, but as far as I know the best you might get would be around the time his mother died. I would look around late March to early/mid April 1940. That might have been the best time for him to talk about it since it would have been really relevant and not too out of left field for him.
