Erica,
I know of a Clarence Uffelman which seems to fit your timing profile. However, I'm unaware of any Pennsylvania connection.
Clarence George Uffelman born March 26, 1905 in St. Joseph Missouri. Served in the U.S. Navy from April 1, 1942 until November 29, 1945. Died November 23, 1968 in Eastland, Texas.
Let me know if this helps.
