"John Bank d. July (5 mo.) 5 1683 in Chelmsford. His widow Hannah m. Joseph Baker b. 1670 [error for 1660], s. John and Susan (Martin) Baker."
According to Chelmsford vital records, John Bank/Bauk and wife Hannah had three daughters born between 1666 and 1670, including Hannah born 1666. Since John's widow Hannah had a documented marital history subsequent to his death, it is virtually certain that the Hannah who married Joseph Baker was the younger Hannah rather than the widowed mother.
