On September 1, 1643, Mary Bradley married Thomas Leaver. This is our earliest record of her. She may have been a sister of Daniel Bradley who came to New England in 1635 (aged 20) in the Elizabeth, and settled at Haverhill. However it seems to the writer more likely that she was the widow of John Bradley, mentioned in the History of Salem as an early settler. John Bradley died "the fourth month 1642" and his will, probated at the Suffolk County court, 29th of the 5th month, says "he had nobody to give his estate but his wife, only some of his clothe & tooles he gave to his brother in lawe, William Allen." The will does not mention his wife by name, and so far efforts to discover who she was have been unavailing.
