The Natural Bridge Line of the Wigton Walkers traces descent from Samuel Walker and Jane Patterson of Natural Bridge Virginia. His descendants form the core of Group 8 of the Walker YDNA project. White 1902 identifies Samuel as the grandson of John Walker I of Wigton Scotland. It is not clear that this is the case. Others who also trace their ancestry to John Walker I show a different YDNA signature, and correspond to Group 33 of the Walker YDNA project.
