William Grey, 9th Earl of Stamford

William Grey, 9th Earl of Stamford (18 April 1850 – 24 May 1910) was an English peer.

He was married in London in 1895 to (Elizabeth Louisa) Penelope Theobald, daughter of the Revd.

[1] On the death of his first cousin Harry Grey, 8th Earl of Stamford in Africa in 1890, he inherited the titles of Earl of Stamford and Baron Grey of Groby and the 3,000-acre (12 km2) estate at Dunham Massey in Cheshire.

Following a delay whilst the House of Lords considered the legitimacy of the 8th earl's son's claim to the title, he moved in 1906 to Dunham Massey to take up residence in the remaining family seat, which had been empty for many years.

Once there, he set about modernising the electrical and plumbing systems and redesigning the interiors with the help of the furniture historian and connoisseur Percy Macquoid.
