Are these Floyds that you mentioned the brothers of Capt. John Floyd of Mecklinburg Co. Va. who married Nancy Andrews? I have a book entitled Early Floyd's of Pike Co. Ala. and Some of their Decendants. and on page 17 in the book there is listed a Fredrick, William, John, and Charles Floyd. These are the grandsons of Nathaniel through his son John on Norhthampton Co. Va,. I realize that this Fredrick is a generation or 2 earlier then the Fredrick who settled in Horry Co. SC,. Thought this might give you a lead.I have heard from several sources of the family in Pike Co. Ala. that there are a some errors in this book. I have found some concerning my Line. Maybe they just meant to give probable lineages concerning the earliers Floyds in Isle of Wight, Northhampton, and Accomac Cos. Va.
