The number of nurses grew over these years although they were often untrained. In 1867, there were fifteen paid nurses. In November 1884, Miss Ella Pirrie was appointed Superintendent and Head Nurse. She knew Florence Nightingale and in December 1884, Miss Nightingale sent a Christmas present to Miss Pirrie for the children in the Infirmary. Shortly after she was appointed, the Guardians approved a uniform for the paid nurses, and a distinctive apron for the unpaid female attendants. Under Miss Pirrie, nursing training began for the first time in Belfast and the first person, Miss Craig was sent to Dublin to sit a nursing examination. Nurse Craig was appointed Superintendent in 1892. The maternity unit was first established on the site by Dr. John McLeish in the late 19th century and then expanded to become the Jubilee Maternity Hospital, moving into new purpose-built premises on the site in 1935.
