Harrison Aldridge (1821-1905) lived in the Watauga district of Watauga County, North Carolina. He was married to Jane "Jinsie" (1823-bef. 1900) and worked as a farmer. They raised Mary (b. 1848), Martha (1850), Samuel (b. 1862), Harrison (b. 1864), Sarah J. (b. 1866), and Monarca (b. 1870). Harrison's family was the only Aldridge family in Watauga County.
