GEORGE HENRY STINEFORD JR. was born on January 26, 1873 in Pennsylvania to George H. Stineford and his wife, the former Louisa Rich. His father, a naval veteran of the Civil War, worked as a printer in the 1870s and early 1880s, and later worked as a plumber. When the census was taken in 1880 the family, which included younger sister Sarah "Sallie" Stineford, lived at 1244 Woodbine Street in Philadelphia. The family had moved to New Jersey in the early 1880s, and two more daughters came, Martha and Mary. The 1887 City Directory shows the Stinefords at 1134 South 3rd Street in South Camden.

In the late 1890s George Stineford married Lillian May McLaughlin. Sadly, she passed away at the age of 21 on January 16, 1900. He never remarried. The 1900 Census shows George Stinford Jr. living with his parents and sisters at 1134 South 3rd Street in South Camden. He never remarried. George Stineford Jr. was then working as a tin and sheet metal roofer. 

George Stineford Sr. sat on the jury that convicted Paul Woodward of murder in he first degree in November of 1902.

Around 1905 George Stineford Jr.'s sister Sarah married Walter A. Mertz. Both Stineford and Mertz would go on to have long careers with the Camden Fire Department, Mertz eventually rising to the rank of Chief of Department.

George Stineford Jr. was still working as a tin roofer when the 1906 City Directory was compiled. By April of 1910 he had been appointed to the Camden Fire Department. He was still living at 1134 South 3rd Street when he registered for the draft on September 12, 1918. By January of 1922 he had moved to a boardinghouse at 322 Sycamore Street run by John and Mary Shaw. By the end of 1926 he had moved to 320 Sycamore Street. He was still working for the Fire Department at that time, according to the 1927 Camden City Directory. George Stineford Jr. is not listed in the 1929 edition, but was in all probability still living in Camden.
