Elizabeth Porter (née Jackson; c. 1589 – ????) was the 11th great-grandmother of Cometan, classified as one of Cometan’s distant maternal ancestors in the Prescott family line. Elizabeth is recorded as having been the wife of Alexander Porter (1585 – 1636), with whom she raised at least one son named Henry Porter (1609 – 1638). Details surrounding Elizabeth’s death remain unknown although she is one of the earliest known ancestors of Cometan in the Prescott family line.
In Cometanic ancestry, Elizabeth is classified as part of the 13th generation retrograde, thus categorising her as a distant ancestor of Cometan.
