Jo-Ann (known prior to her retirement 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 at the Withington Hospital in Manchester, qualifying in 1944. After eight years in general nursing she joined the QARANC (Queen Alexandra's Royal Army Nursing Corps) in 1952. Working mainly in nurse training, she served in the UK, Libya, Cyprus, Hong Kong, Germany and Singapore. In 1963 she was awarded an Associate Royal Red Cross (ARRC) medal for exceptional services in military nursing.
Jo-Ann returned to England permanently in 1970 and worked at the Cambridge Military Hospital in Aldershot prior to her appointment as matron at the Royal Herbert Hospital in Woolwich. By the time she retired, in 1975, she had attained the rank of 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.
