Sophie was born to Tobias and Mary Schantz on May 4, 1869 in or near Campden, Ontario and raised alongside her seven siblings; Orpheus Moyer Schantz, Etta Lydia Mary Schantz, Austin Tobias Schantz, Franklin Abram Schantz, Arthur Benjamin Schantz, Florence Annie Catherine Schantz, and Herbert Cecil Palmer Schantz.

In 1870 Sophie and her family moved to the village of Hawkesville in Waterloo County. In 1877 Sophie and her family moved to Conestogo, Waterloo County and later to Berlin (now Kitchener), Ontario in 1884.

As a young adult, Sophie worked as a dressmaker. In 1884, she stayed with her brother Orpheus and sister-in-law Carrie in Chicago, Illinois. In 1897 she enrolled in a two year kindergarten course at the Chicago Froebel Association’s Jones School in the city. She received a license to teach in Chicago in 1899 and taught there for a short period.

Sophie returned to Berlin (now Kitchener), Ontario following the death of her sister Etta in 1900. She planned to help Ward White, Etta’s husband, raise his infant daughter Dorothy. Around 1902, Ward proposed marriage to Sophie and asked her to move out west to homestead with him in Alberta. Sophie declined his proposal and remained in Berlin (now Kitchener), Ontario.

Sophie was unable to teach in Ontario with her license from Chicago, Illinois. Instead, she worked at Woolworth's Five, Ten & Fifteen Cent store. She helped her sister Florence acquire a job in this store as well during the 1920s.

Sophie retired in the 1930s and subsequently kept house at her family home at 43 Schneider Avenue in Kitchener, Ontario.

Sophie owned and played a reed organ. She enjoyed quilting on large frames in her home with friends from church.

By 1950, Sophie suffered from dementia and was confined to a wheel chair. She was eventually taken to Scott Pavilion at the Kitchener-Waterloo Hospital (now the Grand River Hospital) where she stayed until she died on October 8, 1958.
