I am not related to these people, but according to a book I have, "William Bartlett, Sr. (later Barclift) was an official in Virginia before coming to North carolina.Hath. Vol. 1, page 92 speaks of land having been granted in Isle of Wight Co., VA, by Right Honorable Wm. Bartlett on Sept. 16,1663."A William Bartlett I died in Perquimans Co. before July 26, 1698 when his will was probated. (I don't know if this was the same man.) William Bartlett II married Ann Durant.Isle of Wight is quite a distance from Fauquier, but I guess they could possibly have been there also, so don't discount the research completely.
There is further information about these people in this book.
