"… (Thomas) Powell … On September 29, 1681, he executed his will, … His wife, Priscilla, was mentioned in his will as living in 1681."
It is clear from Mrs. Alcorn's abstract, NEHGR 81:130-31, that the "wife Priscilla" referred to in Thomas Powell's will was his daughter, Priscilla (Powell) Thompson who died in 1726, rather than his wife Priscilla.
