Ok, you have Henry son of William & Eliz Chowning born June 21 bap July 12 1741? Then he married Eunice Baily per marriage bond, Lancaster Co., VA 24 Aug., 1769. I have the translation from the Northern Neck of VA Historical Magazine not a copy of the actual record. Henry second marriage is listed in the Parish Register of Christ Church, Middlesx Co., VA. This is to Margaret Allen on 11 Sept 1785. His death is listed in that same register under Capt Tuning for 11th July 1795. There was a Will of Elizabeth Collins around 1804 which listed Bailey Chowning son of Henry Chowning dec'd..., this is my ancestor and I've never had to prove any of the others. But was given their names. I email a cousin who is from Henry's son John who married Elizabeth Lilly. James, Anne and Elizabeth are from the second wife Margaret Allen.
