Two years later, in 1941, she did her training with the WRAC in Inverness and was commissioned into the ATS as a lance corporal four months later.

She was appointed an Honorary Aide de Camp to Queen Elizabeth II om 15 September 1964 and became a Dame Commander of the Order of the British Empire in the Queen's birthday honours of 1965.

She met Brigadier Mortimer Kelleher MC, a medical officer. They corresponded for many years before marrying in 1970.
