I am pretty much at a standstill over William Waddle. By his granddaugher I am descended from the Cathey family of Mecklenburg County, NC, twice.
Unsourced information given to me has William as a son of a David Waddle,( b. abt. 1735 in County Derry, Ulster, d. aft. 1800 in Abbeville District, SC) and a Mary Mose (b. abt 1740, d. ft 1790). They may have existed, but I haven't found out if there is a documented connection.
Since my time on WikiTree, I am becoming a Grinch, not trusting anything anymore. Check out the profile for all I've been able to find out about William. (His wife is unsourced, too.)
