Thomas was the son of Berry S. (1787) and Mary (Taylor) (1805) Rigdon. He was born in Appling County, GA. He married Rebecca Webb (Aug. 14, 1828), Dec. 18, 1845 in Camden County, GA. They had eight children:

William (1847)
Eliza A. (1850)
Mary A. (1851)
Berry S. (Apr. 12, 1852)
Lydia Ann (Aug. 30, 1851)
Martha Ann (Feb. 15, 1855)
John A. (Feb. 15, 1858)
Sarah A. (1860)

The 1850 GA Census lists Thomas, his wife Rebecca (Webb) 24, and 1 daughter, Eliza A, age 1. He is also listed in the 1860 Irwin County, GA census.

The 1850 census shows that Thomas had a 50 acre farm in Appling County, GA. Thomas moved from Appling County to Irwin County about 1855 and settled in the present Chula district, a section of Irwin cut into Tift County in 1905. He was a member of the Irwin County Grand Jury in the April term 1858. He bought a farm and lived there until shortly before his death. The 1860 Irwin County, GA census shows the family there. His widow reared the children to maturity and lived on the home place until her death May 1, 1899. She was buried at Zion Hope Church, Tift County.

Zion Hope Church was founded in 1859, thirteen years before Tifton was settled. The first services were held in a log building on land given by Thomas. Today, Zion Hope Baptist Church is a thriving Southern Baptist Church on a beautiful site overlooking two lakes. Ed Rigdon owns 250 acres of the old homesite northeast of the church property. The farm today is primarily part of the Georgia Agricultural Experimental Station just north of Tifton and there is a large billboard type sign near the Agrirama which says, "Rigdon Farm - State of GA Experimental Station". The state has recreated an old 1800's style homestead and visitors can see just what if was like for Thomas and Rebecca to live and work the old homestead. The Agrirama is located right on Interstate 75 north of Tifton and the farm stretches several miles north of there.

Compatriot John Rigdon is the great-great-great grandson of Thomas Rigdon through his son, William.
