G.G. Heffelfinger was a Presbyterian and later United Church minister, whose Saskatchewan pastorates included Buchanan, Grenfell, Vanscoy, Melfort, Sixth Avenue United Church (Regina), and Watrous.

Born in Nebraska, Heffelfinger and his family moved to Drinkwater, Saskatchewan, in 1907. He attended the University of Saskatchewan, receiving his Bachelor of Arts degree in 1916. During the First World War, he served as a stretcher-bearer with the Canadian Medical Corps (12th Field Ambulance) overseas, and was awarded the Military Medal. After the war, Heffelfinger pursued theological training, at New College (Edinburgh) and St. Andrew's College (Saskatoon), and was ordained by the Presbyterian Church, in 1921. He married Jean Watkins, in 1922.

Heffelfinger served as minister in Buchanan, Saskatchewan, 1921–1924, and Fort William, Ontario, 1924–1929. He received his Bachelor of Divinity degree from United College (Winnipeg). Returning to Saskatchewan, he served in Grenfell, 1929–1933, Vanscoy, 1933–1934, Melfort, 1934–1936, and Oxbow, 1937–1942. After receiving a Bachelor of Education degree, he became Saskatchewan director for the Canadian Legion Educational Services.

After the Second World War, Heffelfinger served as minister at Sixth Avenue (later called St. John's) United Church, in Regina, 1946–1956, then at Atwood and Springfield (London Conference), in Ontario, until he retired, in 1962.

Morse Pastoral Charge was formed as a new United Church charge in 1925, part of Swift Current Presbytery and consisting of Morse and Ernfold appointments. (Later addition Herbert also formed that year, as a separate Mission Field in the same presbytery, as had the augmented Chaplin Pastoral Charge, in Moose Jaw Presbytery.) Around 1946, Herbert was added to Morse Pastoral Charge. Chaplin joined the charge ca.1958 and it was renamed Morse-Chaplin Pastoral Charge.

Sometime between 1946 and 1951, the charge joined with Fiske to form Herschel-Fiske Pastoral Charge, with points at Anglia, Fiske, Herschel, and McGee. Around the mid-1950s, the name had returned to Herschel Pastoral Charge, as of 1962, made up of Herschel, Anglia and Stanraer.
