Trying to find parents of Rachel Moffett from Berkeley Co, [W]VA

Joseph Close m Rachel Close Nov 21 1793 Berkeley Co [W]VA by David Young, Minister. William Moffett m Elizabeth Cook 5 Dec 1793 Berkeley Co [W]VA by David Young, Minister. Brother & sister married 2 weeks apart by same minister? The only logical father with tax records from the county is a Walter Moffett. In fact he is the only Moffett with tax records 1780-1795. Walter Moffett married a Susannah Hilliard 25 Jan 1773. The eldest female child of Joseph & Rachel Close was a Susannah. Can any Moffett researchers help?
