Quite an old set of messages but maybe someone will notice this.
I suspect Notliff was John's brother and most of the kids listed in "A History of Monroe County, West Virginia by Oren Frederic Morton, McClure Company, Incorporated, 1916. p. 409 (a Google book) may be John's kids. In the book under the name Taylor it says "Notliff lived on Greenbrier River. C [children]: Anna (William Johnson), Nancy (Isaac Milburn), William (Florence Graham), Elizabeth (Samuel Gwinn, Jr.), Mary (Joseph Gwinn of James).
Knotliff's will dated 1806 lists wife Susanah and kids James, Mary, Rachel, Margaret and Sarah, all apparently at least age 18 in 1806.
So that would mean John and Mary's kids were Anna, Nancy, William, and Elizabeth, although they may have also had a daughter Mary.
It appears the Nancy among the list married to Isaac Milburn is the daughter of John and Mary - this based on the sale of John's property in Butler Co, OH in 1820 by his son Robert and daughter Jane Wright nee Taylor to Isaac Milburn. Also I understand Elizabeth Taylor's 1803 marriage to Samuel Gwinn was witnessed by John Taylor.
The entry in Morton's history is followed by another interesting comment, "Another Taylor pioneer married a Vass. Both are buried at Johnson's Crossroads."
So was this other Taylor related to John and Knotliff? Since a Johnson married John's (or Knotliff's?) daughter Anna, might this be an indication of a family connection?
Also on page 487 under Appendix H, a list of Monroe citizens in 1799, is "Taylor: John - Notliff". What I conclude from this is there were two TAYLORs in Monroe at the time, John and Notliff. Maybe in the entry on page 409 the author confused Notliff for John.
John's widow Mary may be the Mary Taylor in Monroe, Monroe, VA in 1810.
