Will of "Moses Chamberlin of Walpole ... Husbandman: Being very Sick and weak in body", dated 18 Oct 1766, proved 14 Nov 1766, names wife Debroah; daughter Mary Partridge; daughter Sarah Chamberlin; son Moses Chamberlin. Son Moses to be executor.
Neither father appears to have a probate, and no evidence tying Moses to either father has been located. The marriage in Boston and settling in Norfolk county seems more consistent with Abraham of Boston than Thomas of Chelmsford.
