Thomas and Sidney Russell

Looking for information on Thomas and Sidney Russell and their family. I have found a marriage record for 1837 in Blount Co for a Thomas Russell and Sidney Ogle and I would like to find out if they are the parents of my gggrandfather Merandy R Russell born 1851 in Monroe Co Tenn. My gggrandfather was one of thirteen children born to a Thomas and Sidney Russell and I would like to find out if this is the same couple. Will share all information I have on Merandy R Russell's decendents. Thanks for your timeJaime
