John Collins

The profile of Katherine second wife of George Allen of Sandwich is listed as "died before June 7, 1656." But a deed from Henerey and Samuell Allin of Boston to George Alline of Sandwidge, land in Sandwich given by father George Allin dec'd, deed with consent "of our mother to say now Kathren Collins who hath interest therin during her life," deed dated 10 July, 1656, witnessed by John Collins (Family History Library: Plymouth Colony deeds, volumes 1-6 v. 3, film 0567789, item 2, p. 7). So Katherine died after that date.

John Collins died on the 29th of May 1670 (according to inventory, citation 2), and Gideon Allen son of George and Katherine was granted John's administration on the 27th of 5th month 1670 (27 July 1670, citation 1). Citations: 1) Family History Library: Suffolk County, MA, probate records, new series v. 1, 1636-1766, transcript, film 594359, p. 480; 2) Family History Library: Suffolk County, MA Probate Records, v. 7, film 584128, item 3, transcript, p. 73-74. There is no mention of Katherine (unknown) (Allen) Collins in his probate records, suggesting that Katherine died after Henry and Samuel's deed in 16 Jul 1656, and before John Collins death on 29 May 1670.
