That makes perfect sense. My father came over in 1917 when he was 3, but waited till 1937 to get his Naturalization. I'll bet that there were a lot of applications back there in order to enlist in the service. My father applied for a duplicate in 1942, which I have. Unfortunately, though I know the exact ship name, port of Departure and Arrival date in NY, I can't find him on any ship manifest or Ellis log to check the theory. Thanks for your help!
