Right, Peter Turney Jr was sheriff of Spencer County in the State of Franklin - which I think would be the area of Hawkins County Tn today. The capital of State of Franklin was Greeneville.....and I know he was also around the Knoxville area. He was around the Watauga - being a surveyor he was all over eastern TN. He also had a lot of land in various places so it is difficult to figure out where he might have married Francis Haines - I am trying to find her family.
The Turneys lived near Edinburg Virginia - early 1774 finds the two sisters - a Teeter and a Beeler - on Beaver Creek between Abingdon VA and Bristol. Eve Turney Teeter is buried on that property and I think it is Scott Co VA today. The two brothers were a bit west and north of Bristol so I guess that would put them also in VA - 1776 Fincastle County and 1777 Washington Co VA. But it was not long before they were over on Cinch River, around Rogersville, Carter Valley. One of them in 1780 registered four pieces of land in that area, one being near Bull's Gap, etc. German Creek is mentioned in a some of the land records. I put that as being in Hawkins County or during the State of Franklin it would have been Spencer County.
Henry Turney was basically a farmer - but he was on the Cumberland at Mansker's station in time in 1780 to get his free 640 acres of land for defense of the fort.
Peter Turney Jr......he was often off to fight Indians, he was with Sevier, and that group....Andrew Jackson was his son's godfather. So he was not only a surveyor and land speculator, but also a politician. His 3 sons all became lawyers - Sam Turney in White Co TN, James Turney attorney general in Illinois, and Hopkins Lacy Turney as TN senator and father to Gov. Peter Turney.
But no one seems to know anything about the family of wife Francis Haines/Haynes. I have found a Hynes or Hines family in early Nashville area.....since Peter Turney owned land over there I thought that might be relatives, but it was after they would have married.
There is a 1777 Washington Co VA petition with names of many of the early settlers - many actually living in what became TN rather than VA....but as you say, they at the time thought they were still in VA. Peter and Henry Turney are on there as are brother-in-laws Teeter and Beelor.....and so are a lot of my other relatives such as Hawkins, Linn/Lynn, Ramsey, and so on. I have a copy if you would like one let me know.
