David, The cite for the birth of "Susanna Bryce, daughter of Martha Aldrich, born July 2, 1774" is: Vital Records of Northbridge, Massachusetts To The Year 1850, [Boston MA, 1916], 26. Inasmuch as Northbridge was set off from Uxbridge, it might well be that Martha Aldrich is the same born at Uxbridge, daughter of Peter and Esther Aldrich, July 25, 1779. Peter Aldrich, Jr. married (int.) Esther Comstock of Providence on Feb 8, 1745/6 The cite for the above is: Vital Records of Uxbridge Massachusetts To The Year 1850, [Boston, 1916], 17 (birth); 202 (marriage). I did not find a marriage nor death for the Martha Aldrich in the Uxbridge records. Jan Delorey
