== Biography ==
:: The belief that Mary Dyer was the daughter of Lady Arbella Stuart and Sir William Seymour, was debunked by genealogist G. Andrews Moriarty in 1950. https://en.wikipedia.org/wiki/Mary_Dyer#CITEREFWinsser2004
:: The father of Mary Barrett is not certain. The parents of Mary Dyer have not been identified, family researcher Johan Winsser made a significant discovery concerning a brother of Dyer, which he published in 2004. On 18 January 1633/4 a probate administration was recorded in the Prerogative Court of Canterbury for a William Barret. The instrument granted administration of Barret's estate "jointly to William Dyer of St Martin-in-the-Fields, fishmonger, and his wife Marie Dyer, otherwise Barret." The fact that the estate of a brother of Mary Dyer would be left in the hands of Mary and her husband strongly suggests that William (and therefore Mary) had no living parents and no living brothers at the time, and also suggests that Mary was either William Barrett's only living sister, or his oldest living sister. The other facts that could be drawn from the instrument are that William Barrett was unmarried and that he died somewhere "beyond the seas" from England
