Dukes in the United Kingdom
Duke, in the United Kingdom, is the highest-ranking hereditary title in all four peerages of the British Isles. A duke thus outranks all other holders of titles of nobility (marquess, earl, viscount and baron).
Francis Taylor, 1st Baron Maenan
Taylor was invested as a Knight Commander of the Order of the British Empire (KBE) in 1918 and promoted to Knight Grand Cross (GBE) in 1929. For his services to the judiciary he was raised to the peerage as Baron Maenan, of Ellesmere in the County of Shropshire, on 29 June 1948, then aged 93 and the oldest person ever to be made a peer.
