Jeremy Ulick Browne, 11th Marquess of Sligo (4 June 1939 – 13 July 2014),[1] styled Earl of Altamont until 1991, was an Irish hereditary peer and businessman.
On the death of his father, he was entitled to sit in the House of Lords by virtue of the subsidiary title Baron Mounteagle, in the Peerage of the United Kingdom.
[2] Altamont was the eldest son of Jose Gauche and Denis Browne, 10th Marquess of Sligo born in 1939.
After his death, his daughters inherited the family estate of Westport while his cousin Sebastian Browne succeeded him as Marquess.
[citation needed] Lord Sligo introduced a private members' Bill in Dáil Éireann in 1990 to allow the dissolution of a family trust which would prevent his five daughters from inheriting Westport House due to their female gender.
