I have just recently found your ref. in Patent book 6 by Nugent. In book 2, is shown John Walker recv'150 ac.Ware River and Trans.3 persons, one of whom is Leonard Ambrose.,29 Jan. 1651. I am interested because my ances. Ambrose Acree(b.1788) of Kg.Wm.Co.,Va.had a brother(b.1791) named Leonard and it seems like a possible link somewhere.I am searching all records but nothing else so far. Let me know if you find something & I'll do same.
