Does anyone know other children of Peter Robinson. His dau. Hannah mar. Wm. Herring 28 Dec 1786 in Augusta Co. Witnesses were Thomas and John Robertson. Can I assume that they were her brothers? Would a man born in 1769, thus 17, or maybe barely 18, in 1786 be old enough to be a witness at a mar? thanks for any help with any of these names Barb
