Jack Cothern and Lavica Vann are my g-grandparents, maternal side. Yes your Shawnee connection caught me by surprise. I have seen mentions of Choctaw, Chickasha, but mainly Cherokee. Will check out the Shawnee site. I do have contact with some Cotherns in Oklahoma, Arizona, Colorado, and California. We are scattered all over Texas. Is a lot of fun chasing the different branches.
