In November 1960, Ashley had met Hon. Arthur Corbett (later 3rd Baron Rowallan), the Eton-educated son and heir of Lord Rowallan. They wed in 1963, but the marriage quickly broke down. Ashley's lawyers wrote to Corbett in 1966 demanding maintenance payments and in 1967 Corbett responded by filing suit to have the marriage annulled. The annulment was granted in 1970 on the grounds that Ashley was male, even though Corbett knew about her history when they married.
