I have I think three sources to quote so I have shortened them to, I hope make the point I believe I have gained from their pages.
First, regarding the Green River Association of Regular Baptists I cannot find any mention in the records available to me. This does not mean they do/did not exist, but only that I have yet to encounter them.
What I have found that I thought might remotely be related is the following:
"Of the first twenty five Baptist preachers that settled in Kentucky, twenty are known to have been Separate Baptists in Virginia and North Carolina; of the other five, only Joseph Barnett is known to have been a Regular Baptist. Yet, after they settled in Kentucky, eighteen of the twenty-five subscribed to the Philadelphia Confession of Faith, and identified themselves with the Regular Baptists. (Spencer, History of Kentucky Baptists , 107).
This was the second association formed in Kentucky and was formed on October 29, 1785, only 29 days after the Elkhorn Assoc. 'evidently had not heard of the existence' of the Elkhorn Association. There were four churches involved: 1. Severns Valley, constituted June 18, 1781 37 members, no pastor. 2. Cedar Creek, July 4, 1781 41 members, Joseph Barnett pastor. 3. Bear Grass, January, 1784, 19 members, John Whitaker, pastor. 4. Cox's Creek, constituted April 1785, 26 members, William Taylor, pastor.
This group proposed correspondence with the Philadelphia, Ketocton and the Monongahela Associations, without mentioning Elkhorn and assumed the name of Salem Assoc. of Regular Baptists and comprised all the Regular Baptist Churches west of Frankfort. (Spencer, 110)
The Green River Assoc. was formed in 1799, about eight churches in the Green River country. "A list of the churches which went into the organization is not on record, but it is known that the following churches were in the territory of the fraternity: Mud Camp, Mt. Tabor, and Sinking Creek in Barren County; Brush Creek and Pitmans Creek in Green County; Dripping Springs in Metcalfe County, which left the Salem Assoc. on account of the Slavery issue was a member of Green River until 1803, when it returned to the Salem Association." (Masters, A History of Baptists in Kentucky , 70).
I thought you may recognize some of these church names which I have been able to track down, not included, but also in the Assoc. was Mt. Tabor of Barren County, which is the oldest church in this county.
Here are their respective messengers:
Beaver Creek Mesgrs: Carter Tarrant, Jacob Locke, Henry Brynton, John Murphy
Brush Creek Mesgrs: Benjamin Linn, WM. Matthews, WM. McMurtry Johnston Crayham, James Goldsby
Pitman's and Robinson's Creek Mesgrs: Jonathan Cowherd, Abraham Harding Philip Crowder, John Chandler
Sinking Creek Mesgrs: Alexander Davidson Thomas Crawford, Daniel Green
Trammel's Creek Mesgrs: Elijah Summers Jonathan Lathan, Benjamin Balas, Charles Harper
Russll's Creek Mesgrs: John White, Henry Hatcher
Sinks of Beaver Creek (Dripping Springs) Mesgrs: Robert Stockton , Robert Smith, WM. Bishop
Barren Mesgrs: Richard Skaggs, Isaac Dale, Henry McGoe
Mill Creek Mesgrs: John Mulkey, John Wood, John Compton, T. Sullivan
(Robert Stocton is also mentioned in assisting in the formation of a "Strawberry Association, though I find no formal record of this it is mentioned in History of the Green River Association p. 11 the above list is in the same book on pg. 10).
I wondered if perhaps this association had also corresponded with Regular Baptists in Virginia or if perhaps you may have heard some of the names mentioned.
Sorry for the length.
God Bless.
