I agree - there must be a connection.I checked the 1810 census for Campbell County and Elizabeth is listed within eight lines of Kenneth (halfway between them is John Griffith - another signer of the inventory).
Another reason - the daughter of Kenneth who married my Painter? (she is, in fact, my gg-grandmother) Her name is Elizabeth.
Now the bad news - I looked in the 1820 census and cannot find either a Griffith Retherford, nor an Elizabeth Retherford - in Kentucky, Indiana or Illinois. There is an Elizabeth Miller within thirteen lines of Kenneth inEvansville Township, Vanderburgh County.She is over 45, has 2 f 16-26, 1 f 10-16, 1 m 16-26, 1 m 10-16 and 1 m under 10.
There is an Abraham Vastin in the 1820 census for Pendelton County KY and a Daniel Isgrigg is listed in 1820 census for Ripley County, IN.There is no Cornelius Williamson listed, and no Williamsons in Ripley, Vanderburgh or Franklin Cos.
Just as a note - when I ran in inquiry on Abraham Vastine - the first thing that came to my attention was a marriage to a Griffith in the 1750s or so. Possibility here?
My Kenneth - I don't have alot of information, just census records in 1810-1840 and the listing in "Early Settlers of Montgomery County Illinois", published by the The National Genealogical Society Quarterly.It states Kenneth Compton, born btw 1780-1790 (census records say 1771-1776) died on 27 Dec 1840 and prob was from Indiana.It also lists William (b. 1810), James (b. 1807 from Kentucky to Indiana), and Greenberry (b. 1820 in Indiana).
