Hello Gen Rooters-I have a question & perhaps someone out there can help. I ordered some pages of the Byron-Sistler index of the 1850 census for TN. A relative is listed in there and after the names, it has the following: SC T, J-503-543. I assume SC stands for the 1st person being from So. Caroline and the 2nd person, his wife as being from TN. I THINK probably the "J" stands for a county in TN. There's nothing in the papers to explain this. Does anyone know how I can tell for sure what county in TN they were in at the time of the census? I'd certainly appreciate any enlightenment. Thanks. Linda
