Grainger Co TN marriage records: Thomas Walters to Nancy Walters on 3 Dec 1821. John "Waters", bondsman - probably her father or her brother.
Thomas and Nancy are said to have had no children. They were 1st cousins once removed.
1830 Grainger Co TN. 1m 20-30, 1f 20-30
Both this Thomas, born about 1801 and his cousin Thomas Spiers Walters, born about 1804, were in Grainger Co in 1830. They would appear in the census as the same age. In 1840 only one Thomas Walters remained - presumably Thomas Spiers who was still in Grainger Co in 1850 - because his wife was Sarah. The ages of the children in 1840 & 1850 are also fairly compatible.
The only other Thomas Walters/Waters found in Tennessee in 1840 was in Henry County. This is his data. Thomas Walters, 1m -5, 1m 5-10, 1m 10-15, 1m age 30-40 [same age as the two Thomases of Grainger] 1f -5, 1f 5-10, 1f 20-30. He would seem to be the same as a Thomas Waters found in Henry Co in 1830: 1m -5, 1m 20-30, 1f 15-20. The Henry Co Thomas would be a son of Abraham or William Walters.
I do believe I found Nancy living with her brother Joel in Clay Co KY in 1850. She was age 47, born in VA.
NOTE: In 1850 Nancy was a widow and was living with her brother Joel in Clay County, Kentucky. Later she bought a small acreage from her brother Thomas Spiers Walters and supposedly lived near him until she died. Perhaps she did this when Joel and Rachel went on to Indiana. She may have married Thomas Walters 12 Mar 1821. They had no children.
Nancy married Thomas Walters on 3 Dec 1821, Grainger Co TN. He is said to have been b. 1801 and died 1848 in Grainger Co.
