Virgil,
Is it possible that the Wiggerton that you list above could be "Wiggenton" or "Wigginton"? The NPS Soldier and Sailor listing doesn't list a Wiggerton with that unit but there is a Wigginton (possibly spelled with the "e") with that company. I am trying to find info on Wigginton's in the civil war. Also, is there another name for this cemetery as I haven't been able to find any other info on it. Thanks for your help!
