Talbot's survey would have been made under Virginia Grants or The Old Kentucky Grants sections. I do not believe it would quite qualify as a Green River Grant, although some funny numbering went on sometimes. There were Green River Grants entered under the Tellico Grants. Also, the Tellico Grants were south of Cumberland River, and I do not believe Talbot's survey would be there. My guess is that it was an old Virginia grant.
Trouble is, there is no clear demarcation of just how far east the Green River designation went.
Actually, I think you could find the Talbot survey in a few minutes if you looked in Jillson. Most libraries that have any KY references will have Jillson. It is a classic.
