Marie-Josephine Gaudette (Mother Cecilia): American-born Italian supercentenarian

Early life and movements

Gaudette was born in Manchester, New Hampshire, in the city of Manchester and was a native of the United States. In adulthood she left North America and lived for periods in Canada and France before moving to Italy. In 1958 she entered and remained in a convent in Italy, where she was known by the religious name Mother Cecilia. Details of her early family life and the specific religious order she joined are not widely published, but contemporary reports emphasize her long-standing residence in the Italian community from the late 1950s onward.

Longevity and recognition

Gaudette reached supercentenarian status—an informal term for people who live to 110 years or older—and attracted public notice in 2016 and 2017 as a result of a number of contemporaneous longevity milestones. After the death of the Italian supercentenarian and world-renowned oldest person Emma Morano in April 2017, Gaudette became the oldest living person in Italy for a short period. Earlier, following the death of Susannah Mushatt Jones on 12 May 2016, Gaudette had been identified in some reports as the oldest living person born in the United States; she was also described in media coverage as the oldest emigrant from the U.S. on record.

Life in religious service and notable facts

As a nun known as Mother Cecilia, Gaudette led a life centered on her convent community. Contemporary reports and obituaries described her as "the world's oldest nun" at the time of her death, reflecting public interest in the intersection of long life and religious vocation. While long-lived religious figures are sometimes noted in longevity studies, Gaudette's life was reported mainly through human-interest coverage rather than detailed scientific examination.

Context and significance

• Definition: Supercentenarian refers to an individual who has reached at least 110 years of age; such longevity is rare worldwide.
• Migration: Gaudette's life illustrates a pattern of twentieth-century transatlantic movement, including residence in Canada, France, and then Italy.
• Public interest: Her status as an elderly religious sister invited broader reflection on aging, faith, and the care of the very elderly.

Gaudette died on 13 July 2017 at the age of 115 years and 110 days. Her death closed a life that spanned more than a century and that connected small‑scale religious community life with international interest in extreme longevity.
