WILLIAM E. HINCH II was born in Camden on October 22, 1941 to Joseph A. and Elizabeth Hinch. His grandparents, Joseph and Catherine Hinch and their ten children were living at 832 Federal Street in Camden when the Census was taken in April of 1930, they had recently moved from Philadelphia. The Hinch family was living at 403 South 5th Street in South Camden when the 1940 Camden City Directory was compiled, grandfather Joseph Hinch, however, had passed away. Joseph A. Hinch, the oldest son of Joseph and Catherine Hinch, married during the 1930s.

From the 1940 Directory it appears that Joseph A. and Elizabeth Hinch may have already left Camden. By 1956 they were living on Lincoln Avenue in Atco, New Jersey.

Apparently named after his uncle, William E. Hinch II living at 1113 North 18th Street in Cramer Hill when he was appointed to the Camden Fire Department in 1969. He reported for duty in the summer of 1970, first with Engine Company 7 on Kaighn Avenue and later with Engine Company 9 at North 27th Street and Federal Street in East Camden.

When residency restrictions were lifted for Camden Fire Fighters, William E. Hinch II moved to Atco New Jersey, where his parents resided. Sadly, on April 26, 1976 he died from injuries sustained in a car accident that had occurred on April 19. His uncle, William E. Hinch, was still an active member of the Camden Fire Department as late as 1977.
