My gggg-grandfather, Isham Gwin, whose alleged parents were allegedly born, raised, and married near Jamestown, met and, in or about 1775, married Mary Canterbury, daughter of Samuel Canterbury, in Montgomery Co., VA. Isham and Mary owned 24 acres somewhere on Brush Creek (southerly of Pilot Mountain), possibly near her father's farm. They then moved to east Tennessee (then part of NC) where they settled on a 249-acre farm in Crowson's Cove (today's Wear Valley) in Sevier Co. and lived until just before 1820. They later moved to Harrison, Crawford, and finally Orange counties, Indiana where they appeared in censuses and church records from 1820 to 1850 (he died in 1833, she after 1850). Much more is on our website's several pages starting at www.zianet.com/jmcdgwin/genealogyhomepage.htm
. I don't know if she is the daughter of your Samuel Canterbury or not.
