Jo-Ann (previously known as Joan) Treacy was born in 1920 in Carrick-on-Suir, Co. Tipperary to Thomas Treacy and Ellen O'Sullivan (see earlier photo).

Jo-Ann trained as a nurse in Manchester after which she joined the QARANC (Queen Alexandra's Royal Army Nursing Corps). She worked mainly in nurse training and served overseas for many years, working in Libya, Cyprus, Hong Kong, Germany and Singapore. She returned to England in the early 1970s and was appointed matron at the Royal Herbert Hospital in Woolwich, London. By the time she retired, she was an acting colonel.

Following her retirement Jo-Ann moved to the village of Henfield in West Sussex where she became very involved in local life. Jo-Ann, who never married, died in 2003 aged 83.
