Thomas W. G. Inglett was born on February 27, 1839, in Georgia, to Matthew and Annis Inglett. His father was a farmer who owned $500 of real estate by 1850. He grew up in Richmond County, Georgia, and he married Martha Palmer there on February 27, 1856. They had at least six children: Ruth, born around 1859; Catherine, born around 1865; Annis, born around 1867; Thomas, born around 1870; and Roberta, born around 1877. They lived in Richmond County, and Inglett worked as a wheelwright. By 1860, he owned $75 of real estate and $50 of personal property.
He enlisted in the Confederate army on September 10, 1861, and he mustered in as a private in Company C of the 28th Georgia Infantry. The regiment took part in the Battle of Seven Pines, the Seven Days Battles, the Battle of Antietam, the Battle of Fredericksburg, and the Battle of Chancellorsville. He was wounded in June 1862, and two of his fingers were amputated. He apparently remained in the army, and he eventually earned a promotion to corporal.
Inglett returned to Richmond County after leaving the army, and he resumed his work as a wheelwright. By 1870, he owned $200 of real estate. He died in Richmond County on April 13, 1910.
