In 1943, McDonald was recruited to join the
Auxiliary Territorial Service (ATS) because of her bookkeeping expertise. She worked in the British Military Hospital of Kingston, as a medical secretary, typing reports of battle injuries. Upon completing 6 months of service, she was promoted to lance corporal and applied for her additional pay as provided for in the British Army regulations. The
War Office turned down her request, stating that ATS soldiers were not entitled to the increase. Six months later, McDonald was promoted to full corporal and her pay increase was still denied. McDonald viewed the policy as racist, feeling that as she was in a British regiment of the
Royal Army Medical Corps (RAMC) she ought to be treated like other such personnel. She said, "We were British! England was our mother country. We were brought up to respect the
royal family." She fought for, but never received, what she considered
the king owed her as back pay. When the war ended, McDonald's commanding officer put in for her to receive the
British Empire Medal, but her recognition was denied. She believed the denial was because she had refused to clean British officer personnel's private quarters. In 1949, when the ATS was merged into the
Women's Royal Army Corps she signed up for further service. In 1952, she married Jamaican
fast bowler Stanley Goodridge, and they subsequently had a daughter, Amru Elizabeth. Soon thereafter, Stanley won a contract to play cricket in
Durham and he moved to England. After completing a decade of service with the RAMC, McDonald-Goodridge joined her husband with their daughter in England, where she gave birth to their second child, Stanley, in 1957. Once the family was settled in Britain, McDonald-Goodridge returned to her work as a medical secretary. She also became involved in charitable works, community service and educational projects. The Goodridges divorced and she married Michael Mark. She joined the West Indian ex-Servicemen's Association and pressed for them to add women to the title of the organisation, continuing her fight for the recognition of women's contributions to the war effort. In 1980, Mark founded an organisation called the Friends of Mary Seacole, which was later renamed the Mary Seacole Memorial Association. Marking the centenary of Seacole's death, a memorial service was held on 14 May 1981 and since that time, the Memorial Association has maintained the grave site. In 1989, when preparations were being made to celebrate the contribution of servicemen and women on the fiftieth anniversary of the war's outbreak, Mark began lobbying for the inclusion of West Indians and women. In an interview conducted by Jacqui Harper for the
BBC programme
Hear-Say, Mark expressed her frustration that the service of
Black Britons was not known. She applied for a grant from the
Greater London Arts Council and put together an exhibition of photographs that she was able to collect from service personnel and the archives of the
Imperial War Museum for the anniversary celebration. In 1992, Mark finally received her British Empire Medal for her meritorious service during the war. In 1993, Mark was notified that the British Government had created a
bursary fund honouring Seacole to grant £25,000 annually for nursing leadership studies. Mark continued her activism, participating annually in the
Remembrance Day parade until her health no longer allowed her to do so. She was also well-known and respected for her poetry and participation in storytelling events to champion Caribbean culture. In 2001, she was honoured as a member of the
Order of the British Empire. ==Death and legacy==
