Fitzgerald Williams was born on March 29, 1842, in Paris, Tennessee, to Isaac Williams and Adeline Fitzgerald. His father was a lawyer who owned $8,000 of real estate and $5,200 of personal property by 1860. He grew up and attended school in Paris, and he read law in his father’s office.
In 1861, he received a commission as a 3rd lieutenant in Company F of the 154th Tennessee Infantry. The regiment took part in the Battle of Shiloh and the siege of Corinth. He was promoted to 1st lieutenant in December 1861. He mustered out in June 1862, when the army reorganized the regiment.
According to an early biographer, he “returned home and nursed his father,” who was suffering from “ill health.” He eventually returned to the Confederate army, and he was wounded in the Battle of Franklin. He spent the final months of the war helping suppress guerrillas in western Tennessee.
He returned to Paris after the war and earned a living as a lawyer. He never married, and he lived with his siblings for the rest of his life. He died in Paris on February 14, 1917.
