Earl of Birkenhead of Northampton, at the same time as he was given the earldom. The three peerages, like the earldom, were in the Peerage of the United Kingdom. Viscount Furneaux was used as the courtesy title by the heir apparent to the earldom; the title of this viscountcy derived from the maiden name of Lord Birkenhead's wife. He was succeeded by his only son, the second Earl. He was also a Conservative politician and held minor office under Neville Chamberlain and Winston Churchill. However, Lord Birkenhead is best remembered as a biographer. He was succeeded by his only son, the third Earl.
