Some say she was the daughter of Philip Randall (1574 – 1662) and Joane Flush (1578 – 1665). IF Philip Randall had such a daughter, she was not THIS one. See TAG 25:151.
The confusion with her parentage comes from people who are treating George Phelps' first wife, a daughter of Phillip Randall, Philura, and his second wife, Francis, the widow of Thomas Dewey, as the same person.

From Donald Lines Jacobus, "Strong-Clark The Corrector Corrected," in TAG 35:151: "There was also in Windsor a widow, Frances Clark, name of husband unknown, who married 22 Mar 1638/9 Thomas Dewey, and the records of Dewey's estate show that she had one Clark child, also named Mary, who was 12 in 1648, hence born about 1636 and a little older than Joseph Clarke's daughter [of same name bp 30 Sep 1638].

This is proved by two deeds recorded 21 Sept. 1663 in which John Strong called two sons of Thomas and Frances Dewey his 'brothers.' "
