The premiere of the film, Agnes, which tells the story of one of the 19th century's pioneering nurses, Co Donegal-born Agnes Jones, took place in Derry last night as part of the Foyle Film Festival.
Among those in attendance at the Guildhall premiere were three descendants of Jones, two from New Zealand and one from Cambridge, England.
Born in 1832, Agnes Jones grew up in Fahan near Buncrana. She was one of Florence Nightingale's first trainee nurses and spent most of her nursing career at the then infamous Brownlow Hill workhouse in Liverpool.
She tended to thousands of Irish people who fell into poverty after fleeing Ireland to escape the legacy of the Famine. At the age of 32, she was in charge of the workhouse. It had a patient population of 1,500, many of whom suffered from cholera and typhus.
Author Felicity McCall, on whose book Agnes Jones the film is based, said Jones, who died aged 35, revolutionised nursing.
"She made the Liverpool workhouse a model for the rest of the country in terms of its caring attitude to patients, she introduced administrative and financial control for the nursing staff and she made nursing a respectable profession," she said.
The title role is played by Bronagh Gallagher.
