You are correct about the Walkers being a part of our family, however I am not sure about the Walkers you mention.
I have not researched any in Texas. I would like to look into your info. Our Butler DNA does not seem to match anyone on the butlerhistoryinfo site other than descendants of Wm.'s three sons, John, William,& Jesse. We are still looking for a direct descendant of Joab Butler b.1819 m. Celia Hinshaw.
I do understand those random DNA matches. We have a Geo Thompson match whose family is from Greene Co., Pa. Can't figure it out.
Thanks for your info
