Right so we have Maurice Patrick Cronin, and his son Maurice Anthiny Cronin. We know the later went to War.
So the question is , which one was the RFC Vice Pres 1915-1917. It is possible the son , born in 1893 could have been. That would make him 22 in 1915. But I'm thinking is that too young to be a vice president (who was often someone who ran a business in the Richmond area).
