In reply to your question, "Where is Carnaby Veal prior to 1787"........
In the book, "Northern Neck Warrants & Surveys", compiled by Peggy Shomo Joyner, 1987, pg158, Wills from Land Office Records, Prince William County VA..............appears the will of Morris Vele (Veal) dated 9 Apr 1750. It reads, "To my son Carnaby Vele the plantation on which I live....".and it goes on to mention other children and neighbors. I can provide if you do not have this info and are interested. Happy hunting, Joyce in VA
