James Sproull was born on 8 January 1877 at 15 Clyde Street in the Milton district of Glasgow. His parents were Thomas and Mary (Thomson) Sproull, and he was the older brother of Thomas Bannatyne Sproull, who married Martha Muir Forysth's older sister, Jane. James grew up in Glagow and by 1891 lived on 52 Water Street and worked as a stable boy. Ten years later, he was a carter like his father.
In 1911 James lived at home with his widowed mother and several siblings on 9 Milton Street. He continued working as a carter, a profession he held until his death.
On 7 April 1916 he married Martha Muir (Forsyth) Paton, a young widow, at their home on 47 Clarence Street in Glasgow according to the forms of the Original Secession Church. Martha had two children, one who lived with Martha's parents and the other, who lived with her.
James and Martha had at least one known son, Robert Forsyth Sproull, though there may have been more children.
James Sproull died on 24 April 1957 at Stobhill Hospital of arterio-sclerotic valvular disease of heart, congestive cardiac failure. He was 80 years old and had lived with his wife, Martha, at 60 Couper Street in Glasgow before his death.
