George's line was out of Kentucky but I am not sure how he ties into all of them. I know there are books on Quantrill that mention that when the group went to Kentucky that they met up with some Wigginton relatives there. While I grew up doing a lot of genealogical research with my parents, my current focus is less on that end of things and more just on any Wiggintons who fought in the war. While doing so, I have noted family ties when it was pretty obvious (George, William, Molly for example) but otherwise haven't got to into that. I will pass your question onto my Dad (Dave W. of IL) and will try to have him get you what he knows of those ties.

Thanks!
