George W. Britton was born around 1844 in Tennessee to David and Lucinda Britton. His father was a farmer who owned $500 of real estate and $500 of personal property by 1860. Britton grew up in Hawkins County, Tennessee, and by 1860, he was working as a farm laborer. He enlisted in the Confederate army on March 28, 1862, and he mustered in as a private in Company G of the 39th Tennessee Mounted Infantry later that day. He was captured on July 4, 1863, as part of the Confederate garrison in Vicksburg, Mississippi. He was paroled eleven days later, on July 15. He was eventually exchanged, and he returned to the war. He was captured again on August 22, 1864, and Union forces sent him to Chattanooga, Tennessee. He was exchanged the following month.
Britton returned to Hawkins after the war, and he married Adaline Jane Waggner there on September 28, 1866. They had at least three children: John, born around 1870; Neil, born around 1877; and Pink, born around 1879. He earned a living as a farmer. They moved to Robertson County, Tennessee, in the 1870s, and he died sometime after 1880.
