Rosemary moved down to the Kent coast from Essex when she was seven, and was educated in Ashford.
From there she worked in London, firstly in the library at Lambeth Palace, followed by the publicity department of Conservative Central Office. She then moved to Vienna, partly to improve her skiing skills, but mainly to work for the International Atomic Energy Agency.
After two years, and having married her husband, she moved on to Brussels. Both her children were born there and attended the local primary school which helped improve her French.
Rosemary joined the British and Commonwealth Women’s Club, originally to start playing tennis again, but soon became editor of the Club’s magazine, then Chairman of the Club, and ended her time in Brussels as President of the President’s Forum. She also ran a monthly cake stall at the Anglican Pro-Cathedral and attended German conversation classes.
Following her husband’s death, she returned to England in 1997, and studied at the University of Kent graduating in 2003 in Archaeological Studies. In 1999 she was elected to the city council for Chartham ward by one vote.
After three years, Rosemary became Deputy Leader of the Group, and then Deputy Leader of the Council between 2005 and 2007. Subsequently she served for six years on the Executive.
