I am so glad to hear from a relation!I am the great granddaughter of one of the grandchildren of Col William R Cook.The information I have pieced together is that his son, Harrison had a daughter named Blanche Cook, who married my great grandfather, Thad Mason Working IThey lived most of their lives in Nashville, Davidson Co, TN. Although I know my connection comes thru Harrison, and that they had property near Athens, Limestone Co, AL. Do you know the names of your great grandparents? I would love to compare notes. Please feel free to email at email@example.com
Again it is nice to meet a relation, and I hope to hear from you soon!
