When her grandfather died in 1921, Edwina inherited his vast fortune, which included £2 million, the country seat of Broadlands, Romsey, Hampshire; Brook House in London; Moulton Paddocks estate in Newmarket, Suffolk; Classiebawn Castle, Mullaghmore, County Sligo, Ireland; and a seaside house at Branksome Dene in Bouremouth. They married on 18 July 1922 at St Margaret's, Westminster. The monarch's immediate family attended; the then-Prince of Wales (the future King Edward VIII) was the best man. The relationship between the families continues, as descendants have often been royal godchildren.
