Karen, I have a little information on this incident. It does not, to my recollection, mention anything about relationship. I'm sure they were related! My grandfather told me this story when I was very young and said that "the Floyd that killed the Sheriff" was related to his Great Grandfather, Wright Floyd. It's one of those "passed down" stories. This would make the Chester County Floyds related to the Horry County Floyds in some way. I have no idea! I'll look for the info I have and let you know!
