My ancestors the Lockerts came from SC to Montgomery County/Clarksville area and I now live in Cheatham county and could help with the information on the Gibbs and Balthrop family. Both families are quite numerous here. Send me particular names and I will check it out for you. I have a copy of the Red River Settlers but cannot find it right now, think I may have loaned it to someone. I do agree with the earlier message that Along the Warriota is an excellent source too.
