Elizabeth Diana Percy, Duchess of Northumberland (née Montagu Douglas Scott) was born on the 20th of January, 1922, to parents the future Duke and Duchess of Buccleuch.
During the Second World War she served in both the Civil Nursing Reserve and the Women’s Royal Naval Service, and worked on the RMS Mauretania and in Australia.
She married Hugh Percy, 10th Duke of Northumberland in 1946 and went on to have seven children. Her husband ascended to the title after his brother, the 9th Duke, was killed in action in the war in 1940.
The Duchess outlived her husband, dying in Surrey, England in 2012.
Divorce had been specifically forbidden in the 1937 Irish constitution. A heavily Catholic country, there was very strong opposition to the legal breakup of a marriage, just as there was when it came to the legalisation of contraception, which was only made available in the 1980s.
The success of the 1995 referendum was a close thing; the results were just over 50% in favour and 49.79% opposed.
