Yapp was born on 30 October 1879 in
Ardwick,
Manchester, England. Her parents were railway guard Moses Yapp (1849–1926) and his wife, seamstress Sophia Eliza Yapp (, 1850–1888). She was the eldest of their four children. By 1891 Yapp and her sister Annie were living with their widowed father in
Edgbaston,
Birmingham,
Warwickshire, England. He remarried in 1892. (GNC) Yapp became an early and active member of the Poor Law Nursing Association and the
General Nursing Council for England and Wales (GNC), She ardently worked for the registration of nurses. Yapp was elected as "caretaker" of the GNC in 1920 and to the Council of the GNC in 1923. She represented poor law nurses and regional interests as well as defending occupational livelihoods on the council, as the only GNC Council member trained in a Poor Law institution. The GNC's first
syllabus for nurse training, produced in 1925, was influenced by Yapp's pioneering training scheme which she had introduced in 1916 at the workhouse. In her writing on paediatric nursing, she was among the first to advocate for children to be treated as children. In 1925, Yapp resigned from her position of Matron, and from the Council of the GNC, Yapp died on 21 March 1934 at Ashwood House (a private asylum in
Kingswinford,
