John, William and George RISNER all appear on the 1830 Giles Co., TN Census. John and William made land entries in 1831. Between 1830-40 they move elsewhere??

I am looking for Court Records regarding a land dispute between these Risners and another resident of Giles Co. and would like to contact any Risners who descend from John, William or George. Does anyone have access to Giles Co. Court records?? Any help appreciated. Clydene
