Charles Steuart Pingle married Jean McLeay, originally from Ontario, on September 16, 1903. Her parents were both of Scottish descent, with her mother being born in Scotland. Her father worked as a money broker and manufacturer in his hometown of
Watford, Ontario. Pingle and his wife had two children, Robert Warren and Charles Glendining; the latter died in infancy. Robert's son, also named Charles Steuart, was an unsuccessful
Progressive Conservative candidate in the Ontario riding of
Windsor-Walkerville in the
1979 and
1980 federal elections. Pingle was greatly associated with the Medicine Hat community. He sat on many boards, including the Board of Trade, Rotary Club, and Board of Directors of the Agricultural Society. He also belonged to the Sons of England Society and
Knights of Pythias. He also enjoyed
baseball and
curling, where he was president of the board and a
skip of a team respectively. He also took an interest in music as a member of a string quartet and as president of a citizens band. The locality of Pingle, near
Fort McMurray, which was formerly an Alberta and Great Waterways railway station, was named after him in 1925. Also, a street in Medicine Hat, Pingle Street, was named in his honour. ==Death and legacy==
