With grateful thanks to Callan Chevin for information about Margaret Mayne, who was born in Ballinamallard, Co. Tyrone, Ireland in 1882.
Margaret trained as a nurse and worked as a Staff Nurse in the North Staffordshire Infirmary from 1907 until the outbreak of WW1. She died in Harwich Hospital on 20th April 1917. A plaque to the memory of Margaret, who was awarded the Associate Royal Red Cross Medal for her work, was placed in the Chapel of the North Staffordshire Infirmary. Since 2015, this plaque has been situated in the Atrium at the Royal Stoke University Hospital, Stoke-on-Trent, Staffordshire, UK.
Margaret's name is not on my copy of the Commonwealth War Graves Commission List of Female Casualties of the First World War. If anyone knows more about Margaret, please get in touch.
