She had two brothers, Andrew and Ronald ("Polly") both of whom died in Africa during World War II.
Her music was encouraged by the family doctor and she began to compose and study the violin, receiving lessons in Bournemouth with the first violinist of the symphony orchestra.
[1][2][4] After the War Wynne-Jones purchased and managed a bookshop on the King's Road in Chelsea, but it was not a financial success.
An interest in completing landscapes in an abstract manner led her to study with Peter Lanyon in St Ives, Cornwall.
Other group shows were Jefferson Place Gallery, Washington, DC, USA (1959), and in Falmouth, Cornwall (1960).
From the 1960s through the 1990s she exhibited in Britain, Italy, Belgium, Germany, Ireland, Spain, Holland, South Africa, and the USA.
