Evidently people who are saying that John Harris who married Mary Drew was the father of John Harris (m. Avis Hollemon)have not seen the documentation that I have which shows that John, son of John and Mary, did not marry and so could not be the John Harris who married Avis.
John and Mary Drew Harris named their children Newit, Thomas, Drew, Nathan, Anne, Martha, and John*.
*This John, son of John Harris and Mary Drew,in his will of Sept. 15, 1789,mentions his brothers Newit, Thomas, Nathan, sister, Martha Newsom, nieces Lucy Newsom and Fanny Newsom. Executors were Cordell Norfleet and brother Nathan Harris.(Source: SOUTHAMPTON COUNTY, VIRGINIA WILLS; BK I)
In my mind, this proves that the two John Harris's are different individuals.
