Tara, I found a William Joseph Armhold on Ancestry family records. born 5 May 1921, died 1987 in New Brunswick, New Jersey. I checked his Military records: he died on 13 July 1987. At the same time the records for George E. Carman came up: born 30 June 1922, died 15 March 2008. This yours?
Also, 1940 Census, Kings County, NY
Mary Green, age 49 Joseph, age 18 George, age 17 Thomas, age 12 Ruth, age 10
All of the children above are Armholds, so it looks as if Mary married again sometime between 1930 and 1940.
