Cumberland; in May 1758 Edward and Jane conv. land to Robert Wilkinson previously conv. to his mother in March 1722 (this was done to clear up any question of title); had iss.:  NICHOLAS (named in the will of John Barrett in June 1717); poss. EDWARD; poss. WILLIAM WILKINSON; ABRAHAM, b. 7 Sept. 1722; PHYLIS-ANNA, b. 12 May 1725; PROVIDENCE, b. 26 June 1727; UNITY, b. 2 March 1730.
p. 137	Unrelated Corbins... CORBIN, WILLIAM, m. Rachel Wright on 11 Aug. 1745 (131).
Barnes apparently considered William Wilkinson CORBIN not to be the William who married Rachel WRIGHT or, at least, that it was not proven they were the same person.  He also seemed dubious that William Wilkinson CORBIN was the son of Edward, but the deed of 1747 (see below), clearly shows he was their son.

p. 119	16 May 1741, Elizabeth WRIGHT of Baltimore Co., Maryland, to her son, Jacob Wright of same, for love and affection, £35 on the day he marries. Signed Elizabeth Wright. Wit: Thomas Sligh, Thomas Hempstone, and William Corbin.
p. 263	10 Apr 1747, Edward & Jane Corbin of Baltimore Co., Maryland, to their son, William Wilkinson Corbin of same for love and affection, 58 acres... south side of the great falls of Gunpowder River. Signed Edward (x) Corbin and Jane (x) Corbin. Wit: William Rogers and Williams Worthington Jr.
Thomas SLIGH was married to Sophia WILKINSON, d/o William & Tamar (LOVE) WILKINSON, which made Thomas the uncle of William Wilkinson CORBIN.  It would obviously be interesting to know how Elizabeth WRIGHT was related to Rachel WRIGHT.  The important thing about this record is that it shows that the William CORBIN who was connected to the WRIGHTs is the same William CORBIN who was connected to Thomas SLIGH and, thus, the WILKINSONs.
