In 1904, the Duchess took on the lease of 5 Grosvenor Square, Mayfair.[1] She died there of neuritis on 20 November 1909. At her bedside upon her death were her sisters, Lady Lister-Kaye and Emily Yznaga.[2] Her estate, valued at $2,493,131 (an approximate value of $69 million in 2017 rates[citation needed]), was left to her various family members.[3] Her son, the 9th Duke, inherited the Grosvenor Square house, retaining it until 1914 when it became a wartime hospital.[1]
