In the 1850's there were any number of Pursifull's in Knox, Bell, and Harlan Counties in Kentucky. One of the more prolific lines is Joseph, b:1786 in Wythe Co. VA, married to Rebecca Jones. Their children were Esau (1807), Jacob (1811), Issac (1814), Lavista (1821), Henry H. (1837). Of the older boys, the only one I don't have descendant information on is Isaac. Just a guess, but these individuals could possibly be from this tree. The PURSIFULL spelling is fairly closely linked to Peter Percivall (Pursifull)who was the father of Joseph and 11 other children.
