I have in my records a Thomas G. Ratterree born about 1811 in Tennessee. He shows up in the 1850 census (Page 379 of the Tennessee census.) Census shows: Thomas, 39, farmer, Frances, 30, John G. 13, Elizabeth J. 11, xxxx B. 8 (male), Thomas 3, William 10 mo. Thomas and Frances born in Tennessee and children born in Mississippi. (Tallahatchie County) I have the last name of his wife as Kolb, not Cobb. I have some information on their children but none on parents for either side. Don't know if this helps you at all.
