Ok Don this is where I went into left field....

I concur with what you say that John Wigginton should have been married to Mary Ann Fristoe.... I found one 2nd hand source to provence that marriage under that name. However I also have found in the Chariton County Marriage records, Mary Anne Gullet/Gillet marrying our John Wigginton on 28 Feb 1832 with the ceremony being performed by none other than Thomas Fristoe.

So who is Mary Anne? Perhaps this was a second marriage?

I've found scads of information on the internet making Mary Anne Fristoe, Bud Wigginton's mom but it all comes back to the same dubious source / McCorkle's claim. Now I have no reason to think McCorkle had any reason to fabricate the issue, but I get back to the original problem, source documentation indicates there is more to this story than first meets the eye.
