This is Vikky in San Diego...And I have nothing to offer up but some confusion...but I do feel that there are allied lines somewhere in this mixture.
I certainly cannot put any pieces together, but let me tell you what I have..
Edward Wilburn b. circa 1730 (probably lived in culpepper VA..At least some of this allied family did...He was m to Mary St Clair, daugther of Alexander St. Clair of Fauqier Co VA...He later relocated to Surry Co NC and died there in 1806...One of this daughers was married to a Stephen JOnes... Suzannah Wilburn m Jones (sorry I do not have the m date in front of me)...And in this Wilburn line was an Edward Church Dyke Wilburn who was born in TX..Peter's Colony..
And there were some Riggs that fit into this family in some fashion...And some of these Wilburns later settled into Sangamon Co ILL and the best that I can tell you is that these people married into allied families for a hundred years or longer..Whew!
And that's about all the confusion that I can add...I wish I could identify the father of Stephen Jones..who must have been b. circa 1760-70..
