My 4th gr-great grandmother, Sarah Briggs was b.01 Nov 1754 at E. Greenwich and married Joseph Cory of E. Greenwich on 19 Feb 1778. Arnold, in his "Vital Records of R.I." records Sarah to be a daughter of John Briggs, however, in Sarah's application for widow's pension, is an affadavit which states that she is a daughter of William Briggs and is submitted by Elder James Wightman who married them. Does anyone have information that can reconcile the discrepancy ?
