Garnett and Vaughn Family

I am looking for any information on a John and Nancy (Vaughn) Garnett who are listed in the 1850 Census of Jackson County Alabama. John was a stonecutter. The family is listed in the 1860 Census record for Scottsboro, Jackson, Alabama. They had a daughter Martha J Garnett born in 1847 who married a John F. Cody in Franklin County Tennessee in April 1865. After Martha and John married they later moved to Nashville, Tennessee where he was a grocer. The family is listed in the 1870 Nasville Tennessee census record. They had two children that I am aware of. Mary E and J. Wilbur. Wilbur settled in Louisville KY and was my grandfather.

Martha is listed as a widow in the 1900-1920 census record in Louisville Kentucky. Martha later moved to Columbus Ohio in 1930 to live with her daughter Mary E.Davenport and died on September 9, 1930 in Columbus Ohio.

Any information will be appreciated.
