The Gerontology Research Group is delighted to announce the validation of Mrs. Mary Keir of the United Kingdom.

Mary Keir was born in St Davids, Pembrokeshire, Wales, UK on 3 March 1912. She later lived in Llansteffan, Carmarthenshire, Wales. She worked as a ward sister at Llandough Hospital in Penarth, Wales. In either 2011 or 2012, Keir moved into a care home in Llandeilo, Carmarthenshire, Wales. Coincidentally, another supercentenarian Gwenllian Davies (1905–2016) was also a resident of the same home. On 17 December 2020 at 2.30pm, Keir received her first dose of the Pfizer/BionTech vaccine, making her one of the first care home residents in Wales to be vaccinated against COVID-19. Keir became the oldest known living person in Wales, following the death of 110-year-old Amy Hawkins on 9 September 2021, as well as the oldest known living person born in Wales, following the death of Mollie Walker on 22 January 2022.
