A woman in Canada identified a "forgotten" British World War One nurse as her grandmother after seeing her photo on the BBC's Antiques Roadshow.
Carol Jephson said she was "surprised" to spot Olive Buller, who had worked at a hospital that was set up at Wrest Park in Bedfordshire.
In September 2018, English Heritage, asked people to help identify the women who were "backbone" of the hospital.
The conservation body said other nurses were also identified as a result.
