Mary Agnes Moroney (May 10, 1928[1] – October 20, 2003)[2][3] was an American woman who as a child was kidnapped from her home in Chicago, Illinois, on May 15, 1930.

Mary Agnes' kidnapping is the oldest case of this nature in the files of the Chicago Missing Persons Bureau.

[4] In 2023, it was announced that DNA tests conducted with the participation of Mary Agnes' surviving family had determined that the girl had been given the name Jeanette Burchard.

[5] On May 14, 1930, Mary Agnes' mother answered a knock at her door and was greeted by a woman who claimed to have been sent by a social worker to deal with the Moroneys' case.

[1][5] After Catherine disclosed the family's many problems, the woman asked if she could temporarily take Mary Agnes to California with her, adding that she would be unrecognisable and "fat as a butterball".

She stated that she had arranged to get a better job for her husband Michael and offered to take Mary Agnes to a nearby store to buy her some clothes and shoes.

Two weeks after the kidnapping, a woman who identified herself as "Alice Henderson" sent the Moroneys a letter in which she stated that "Otis" was her cousin and that she was "love hungry" because her own husband and baby had died the year before.

[1] In July 1931, an elder Native American woman named Martha Thompson was found pushing a cart to join a circus.

The cart contained a blond-haired, blue-eyed three-year-old girl that matched Mary Agnes' description.

[3] In February 2023, it was announced that DNA testing had determined a link between Mary Agnes's surviving family and relatives of Jeanette Burchard, a Florida resident who had died in 2003 at the age of 75.
