The Vanishing of Mary Wenwood?

As recounted earlier, Gen. George Washington had Mary Wenwood brought his headquarters to answer questions about a ciphered letter she had given to her former husband to pass on.

The woman held out against the general’s questioning for hours. But still under guard the morning after she arrived, she gave up the name of the cipherer: her lover, Dr. Benjamin Church.

After that, Mary Wenwood fades from the historical record. She had every reason to adopt a low profile. Gen. Washington kept her name out of his official report and paperwork. No surviving informal comment on the episode mentions her name. 

But men had a lot to say about her character. Indeed, just as she vanished as a person, she started to appear as a character in a moral fable—the downfall of a doctor.

James Warren, speaker of the Massachusetts house, called her “a suttle, shrewd Jade” and “an Infamous Hussey.” The Rev. Ezra Stiles of Newport said she was “a Girl of Pleasure,” and had carried the ciphered letter “in her stocking on her Leg.” How did he know?

Lt. Ebenezer Huntington of Norwich, Connecticut, told his brother: “the Plot was discoverd by his [Church’s] Miss who is now with Child by him and he owns himself the father (for he has Dismissed his Wife).” Huntington was stationed in Roxbury, far from Washington’s headquarters, and had no link to people in the case. No one closer to the investigation said the woman was pregnant. Some other details in Huntington’s account are wrong. Therefore, unless other evidence turns up, I think this was probably baseless gossip.

Here are further facts possibly about Mary Wenwood.

The 14 December 1775 New-England Chronicle reported that the Cambridge post office was holding mail for a woman named Mary Butler—which was Mary Wenwood’s maiden name.

Mary was the most common given name for women, and Butler a fairly common surname. Wainwood/Wenwood/Wanewood was much less common. Indeed, all mentions of “Wenwood” and its variants in late-1700s New England newspapers lead back to Godfrey Wenwood, Mary’s former husband.

That said, Newport vital records show that another Mary Wenwood, wife of Frederick Wenwood, gave birth to a baby girl named Mary in December 1785, and that couple baptized a baby girl named Mary (perhaps a new one) in June 1787. Even an uncommon name isn’t necessarily unique.

The most tantalizing clues are that a Mary Wainwood/Wanewood was in and out of the Boston almshouse after the war:

• Admitted 6 May 1785, left 30 May 1786.
• Admitted 29 Feb 1792.
• Admitted 12 Jan 1793.
• Admitted 25 Apr 1797, died 23 May 1797.

And that last entry stated that the woman was from Rhode Island.
