Mary Provost-Slocum

Mary E. Provost-Slocum (née Tiriolo) is an American supercentenarian who is the oldest known resident of Connecticut. Her age has not been validated by LongeviQuest (LQ).


Provost-Slocum was born in Greenwich, Connecticut on 19 January 1912. Her parents, Bruno Tiriolo and Carmella Morabito, emigrated from Calabria, Italy, before marrying in 1910. She had four siblings: Patrick, Joseph, Grace, and Mildred “Millie”.

Provost-Slocum moved to central Greenwich in 1951, and remembered the construction of I-95 through Bruce Park. Her occupations included a phone company operator, a waitress, and a switchboard operator for Empire Brush Works. Later, she volunteered for Meals on Wheels, as well as at Nathaniel Witherell, a Greenwich nursing home.

In 1971, Provost-Slocum’s mother died aged 98. On 8 April 1972, aged 60, she married Joseph S Provost. Her father died aged 103 in 1984. Shortly before her 103rd birthday, a bench was installed in local Pemberwick Park in honour of her and her two sisters.

Provost-Slocum became the oldest known living person in Connecticut following the death of 110-year-old Antoinette Davis on Christmas Day 2021. She would reach supercentenarian status a little over three weeks later.
