All I have been able to prove so far is that a James Brumfield came to Virginia in March 1672, transported here by Robert Taliaferro.
Yesterday I went to the Tennessee State Archives to look for the Vestry Book of Abingdon Parrish. I was extremely disappointed that they did not have a copy. I had read in several family genealogies that referred to a vestry record of Abingdon Parrish Church in Gloucester County where James Brumfield lived and in which James II and several other siblings births were recorded.
So I am going to have to search for these records.
The internet archives has a book "Colonial Churches in the Original Colony of Virginia" in which he describes the early colonial Gloucester and Abingdon Parish. According to this book on page 190, the Abingdon Parish had 570 residents from 1677 to 1761. On page 190 and 191, they alphabetical list resident's surnames and among those residents is a Bromfield.
