In addition to my earlier reply, if your county was one of the "burned" counties there is the implied ownership of real property indicated if there is an entry in Column 8 of the 1860 and 1870 Federal Population Census schedules. This, however, does not constitute proof of ownership of any particular piece of land or the location of the land. There are the companion Agricultural schedules which gives additional details such as acreage, livestock, and harvest.
I can only assume the the South Carolina Archives has these schedules. I have never had occasion to use the South Carolina schedules. They were offered to the various state archives when the National Archives decided to dispose of them so they either wound up at the archives or with some historical society. Very few have been microfilmed and none have, to my knowledge, been indexed but the enumerations generally follow the same sequence of the county population schedule so the information is relatively easy to find.
If you can find your ancestor in the Agricultural schedule it may provide an interesting snapshot of farm productivity and life on the farm. Many family historians overlook this excellent source of information.
