Addie May was the tenth of William Sinclair Torrance and Mary Jane Whitcomb's eleven children. Born in Clackamas County, Oregon, she spent her childhood with her large family near Colfax, Washington.

On February 22, 1905, Addie married a Canadian-born farmer and blacksmith named Bonnar Robert Quint from Farmington, Washington, 25 miles northeast of Colfax. Their wedding took place at her widowed mother's home. An account of the ceremony was offered March 5th in the Seattle Daily Times:

"Colfax - Saturday, March 4 - The marriage of Miss Addie J. Torrance of Diamond and Bonnar Quint of Farmington was solemnized at the home of the bride's parents Tuesday, the ceremony being performed by the Rev. H.G. Edgar, pastor of the Colfax United Presbyterian Church, on the piazza of the country house, while the guests, about eighty in number, stood on the lawn in front. The bride was attired in white silk mull, and Miss Quint, a sister of the groom, who acted in the capacity of maid of honor, wore pale blue mull. Earl Kirkman was best man. A large concourse of friends were present from Colfax, Diamond, and Endicott. Mr. and Mrs. Quint went on a wedding trip to Sound points."

The Quints had three children: Marjorie, Raymond, and Leroy, all of whom were born in the state of Washington. The family settled in various places, according to federal censuses. In 1910 and 1920 they farmed at Rockland, Idaho. In 1930, Bonnar worked as a lumber mill blacksmith at LaGrande, Union County, Oregon. He died there on September 15, 1935, at age 65. His body was returned to Washington and he was buried at Farmington.

By 1935, Addie had moved to Oakland, California. As of the 1940 census, she lived with her son Ray and his wife Jeanne, as well as daughter Marjorie Brooks and her baby, Glenda Brooks. By 1945, she had moved to nearby Berkeley. After Addie died at age 79 in Contra Costa County, California, her body was returned to Washington for burial next to her husband.
