I don't know who Alexander's first wife was. I have mention of some deeds witnessed, but I am missing some information. perhaps we could work it out.I don't have a spouse for William Hargis or Elizabeth Richardson. I do have Wm. R. and Martha Gipson. Also Elisha Floyd and Nancy Tucker. And Alex B. Floyd and Mollie. I have that Alex B. Floyd wh married Mollie Richardson was the son of Elisha Floyd and Nancy Tucker. And Elisha was the son of Wm. H. (or T - that may be the one I need to correct) Floyd and Martha MCDaniel. Wm. H. (or T) was the son of Alexander and (Mary) Ann Jackson. Alexander was the son of William Floyd. Mother's name unknown. I have some McDaniel information through an allied line connection surname Box.
William Floyd, Sr. died in Grundy Co., TN leaving a will. Grundy County came from Coffee Co. and Coffee came from Franklin. I am not familiar with the Marion Co., TN Floyds. The Floyd family along with daughter's families of Tubb, Hargis, Moore, and Muckleroy (GA) moved from South Carolina to Franklin Co. about 1810 or so.
I'm trying to work on William Floyd and his son, Alexander for the DAR.
