E.C., Your Marrs line is likely out of Virginia. My Shannon line enters Penn., and then migrates into Giles Co., Va, where the Marrs line enters the family. After the Revolutionary War, they go into Davidson Co.,Tnn., and along the Ky.,-Tnn., border thence upriver to Crystal Hill, Ark., and on into Washington Co., Ark. I hope this is some help.
