‘MARGARET [daughter of Robert and Catherine (Taylor) Fitz Randolph], b. May 1, 1744; mar. in Woodbridge 28 of 8 mo., 1766, “Black” ABRAHAM VAIL, b. Mar. 12, 1744, son of Stephen Vail, Jr., & Esther Smith.’
Unfortunately, between the 1943 publication of this information in NEHGR and the 1950 publication of the book, the same marriage date got applied to two different marriages involving two couples with the same names. See NEHGR 97:338 for what is assumed to be the correct information.
