I am trying to confirm a questioned link.Here' what I know starting with me (direct lineage only)
Roger Eric Nell b. 6/15/1965 Ramona Leslie Anderson b. 7/16/1942 m. Robert Eugene Nell Leslie Orion Anderson b. 8/23/1917 m. Coryne Sarah Powers William Earnest Anderson b. 1884 d. 1965 m. Lillie Pearl Clarkson (John or William) Martin Anderson b.? d.? m. ? ??William Anderson b.1814 d.1861 m. Georgianna Pettigrew ??Col. William Anderson b. 1764 d. 1839 m.Anna Thomas
I do not know for sure whether William and Georgianna are John/Wm Anderson's parents.
Also, I do not know for sure whether William b. 1814 is Col. William's son.
There may be a missing generation between William b. 1814 and Col. William given that Col. William would have been 50 at the birth of William b. 1814.
