Mary Jones (born December 12, 1803 as Peter Sewally) was an American transgender prostitute and soldier. According to The Sun, she would wear "a dashing suit of male apparel" in the day, while dressing in feminine attire and wearing a prosthetic vagina at night to solicit sexual services for men and steal their money. She is most well known for being the subject of a trial in 1836 where she was charged with grand larceny for stealing the wallets of men she engaged in sexual acts with. She is considered to be one of the first recorded openly transgender people in New York history.
