Yes, I agree with your thesis.I have been researching the Yearwoods since the early 1970's.I have the will of William Yearwood who died in Rutherford Cty, Tenn., in 1823.He mentions as his heirs Rebecca Belk (to whom he left his "little pine chest or box which I bought in Halifax") Sarah Haskins, Nancy Byers, and William Yearwood (to whom he specifically left nothing). I also have the will of John Yearwood who died in Rutherford County in 1847 who lists as his son William M. Yearwood.This William M. Yearwood died in McMinn County, Tenn., in 1849. Nancy Byers was the sister of Frederick Yearwood who died in 1821, shortly before his father William.Frederick's widow and sons, Aaron, Robert and William, together with Nancy Byers and her husband, William, left Tennessee in 1826 and settled in Jefferson County, Illinois, where their descendants still reside. The one connection that puzzles me is the William Yearwood who lived in Sweetwater Valley.I do not think he is connected to the Yearwoods/Earwoods in North Carolina who moved to Rutherford County.That William Yearwood is reputed to have been born in Charleston, S.C.His dates do not fit. Incidentally, have you found the record of a Virginia land patent granted to William Yearwood and Francis Whitton on 29 July 1650 on the Rappahanock River.I prefer to think the Yearwoods migrated from Virginia to Halifax (which is right on the Virginia border) and then to Lincoln County and Rutherford Cty. Tenn.There were and still are many Yearwoods in the Barbados and some of them emigrated to S.C.Also, John Harvard, who founded Harvard College, had a stepfather who was Richard Yearwood of London and perhaps the Yearwoods were from Cheshire.A Richard Yearwood was also the cousin of George Yardley, the 1st Royal Governor of Virginia. I would enjoy hearing more of what you have learned.
