Death date based on Nathaniel, 1st child of husband Samuel and his second wife Abigail, baptised 10/12/1679 (assuming the Samuel who married Abigail is the same Samuel who was married to Elizabeth Burgess).
Mrs. Hallett cites Elizabeth's death date as 11/14/1691. I think this may be a different Elizabeth, and that Elizabeth Burgess died before 1679, since Samuel's son Nathaniel by his second wife Abigail was baptised 10/12/1679 (St. John's Church, Pembroke Parish, Bermuda, Register, pg. 17).
