Whitfield Family Genealogy Forum
I do not know where the book can be purchased. I was able to get the loan of Volume II through my local library's inter-lending program, but they could not find Vol. I this way. I bought mine from a "cousin" that had an extra copy.
I would be willing to "look up" specific info for you.
You mentioned Elizabeth Smith. William Whitfield I, had a sister named Elizabeth Whitfield and she married John Smith in 1708. They settled in what became Smithfield, VA. Is this your Elizabeth?
