I found this note online:
From Harrodsburg Historical Society:
Lincoln County KY Early KY Householders 1787-1811
Shows dates when counted:
•Burks, Allen: 09Aug93, 10Apr95, 01Jun96, 04Aug02, 06Jun03, 06Aug04, 23Aug06.
•Burks, George: 28Jun87, 18May89, 02Jun90, 23Jun91, 20Aug93, 20May94, 19Jul00, 04Aug02, 06Jun03., 07Aug04, 08Jul05, 23Aug06.
•Burks, Levi: 06Jun03, 26Aug04, 16Aug05, 23Aug06, 10Jul09, 1811.
•Burks, Mathew/Matthew: 22Jun09, 1811.
•Burks, Rollin/Rolling/Roland/Rolen; 18Jul98, 02Jul99, 31Jul00, 13Jul01, 26May02, 18Jul03, 04Aug04,16Aug05,28Jun06.
•Burks, William: 24Aug87, 19May89, 02Jun90, 21Jun91, 28Sep92, 10Aug93, 04Jul99, 09Jul01, 12Aug02, 1803, 07Jun03, 07Aug04, 16Aug05.
•Burks, WILLIS: 16Aug05, 04Aug06, 1811.
•Burk, William Jr: 09Jul01.
I gather some believe that William Burks was the son of Samuel Burks Jr. and wife Elizabeth of Albemarle County..but a possible additional child (William) was not mentioned in Samuel Jr's will. (Which doesn't completely rule him out as a son because some other provision may have been made for this child. I have seen this before in wills/deeds).
Albemarle Co., VA, WB 2:l0-11, written 5 Jan l743; proved 13 July 1753.
Sorry not to be more helpful.
