Here is some unsubstantiated information from some of the Butler Co., MO, cousins:
Obediah b 1797 VA d 1860 Wayne Co., MO m Elizabeth Canady (1788 NC to 1857 Jackson, East TN) 1809 Rowan Co., NC. Elizabeth was daughter of Sherwood Kennaday Sr.
Obediah was son of George Twidwell, who was son of unknown Twidwell and Mary Simpson. Source was Pedigree Resource File on www. familysearch.org; CD5. I have not checked it out yet. It also included additional information on the John L. White line:
John L. White b abt 1815 Chatham, NC d 21 Aug 1861 Wayne Co., MO; m. abt 1837; son of Luke White and Nancy Bland. I am about to be able to connect Nancy Bland with the Blands of Virginia as I expect to receive some good information within the week which I will forward to you.
