I have records of Frederich Floyd b. 1769 in old Kingston District, SC, with a son, James who could have been born 1790-95. This is derived from Andrew Johnson Floyd who had four sons, one of whom was James. There are several other local Jameses but others are accounted for in later local records.
You may have resolved this by now (I am looking at old records.)Also, I think I saw an old post from you denying A.J. Being the father of these Floyd brothers.
Anyhow, for what it is worth, here it is. Good luck. Henry Bascom Floyd.
