"A sister of Alice Carpenter, q.v., Mary never married, but came to live in her later years at Plymouth, where she died 19/20 March 1687/88 in her ninety-first year, "a godly old maid, never married" (Ply. Church Recs. 1:260). Frederic Kidder, "Letter of Mary Carpenter," NEHGR 14:195, transcribes a letter addressed to Mary at Wrington, Somerset, from Governor Bradford in which he writes, "Sundrie of our ministers (hearing of the peace and liberty now in England and Ireland) begine to leave us and it is feared many more will follow. We do not write these things to discourage you (for we shall be glad to see you if God so dispose) but if you find not all things here according to your expectation when God shall bring you hither that you may not thinke we delt not plainly with you." A footnote in NEHGR 14:196 suggests that the date of the letter, 19 August 1664, in the oldest extant copy must be wrongly transcribed. Internal evidence would place it ca. 1644 or 1646.
