According to Bond’s Watertown234 (with square brackets in the original), “Dea. NATHANIEL LAWRENCE, of Groton, m., in Sud., Mar. 13, 1660-1, SARAH MORSE, b. Sept. 16, 1643, dr. of John and Hannah (Phillips) Morse, of Dedham. [See Memorial of Morse, p. 40.] She d. in Groton, in 1684, and he m. (2d) HANNAH (Anna) _____.

Green’s Epitaphs235 repeats substantially the same information: Nathaniel “is represented in this neighborhood at the present time by numerous descendants. He held various offices in the church and town, and was one of the first representatives to the General Court, under the charter of William and Mary, in the year 1693. He married, first, March 13, 1660-1, Sarah, daughter of John and Hannah Morse, of Dedham, and lived for a while at Sudbury, before coming to Groton. His wife died August 29, 1683, and he married, secondly, Hannah _____. In advanced life he removed to that part of Cam-[p. 244]bridge now Lexington, where one of his sons was living, and here he died March 12, 1746, leaving a large family.”

Note that brothers Nathaniel and Peleg Lawrence married sisters Sarah and Elizabeth Morse.
