Baron Arlington is a title in the Peerage of England which was created, on 14 March 1665, for Sir Henry Bennet,[1] younger brother of John Bennet, 1st Baron Ossulston. In 1672, he was made Earl of Arlington and Viscount Thetford, and was regranted the title of Baron Arlington, with a special remainder allowing it to pass to both male and female descendants, rather than only heirs male, as was customary with most peerages. Its territorial designation is the birthplace of its first holder Harlington, London, which was also known as Arlington.
The 11th Baroness Arlington was the last woman to take her seat in the House of Lords under the provisions of the Peerage Act 1963. She became a member of the Lords on 27 May 1999 and remained in the House until 11 November 1999, when the House of Lords Act 1999 took effect.
