NEWHAVEN, Viscount, a title in the peerage of Scotland, conferred, by patent, dated 17th May, 1681, on Charles Cheyne of Cogenho, descended from an old Northamptonshire family of the name. (See CHEYNE). The principal title was taken from Newhaven, in the county of Edinburgh; the secondary title was Lord Cheyne. Previous to being created a viscount, he had been M.P. for Agmondisham, and as a Scottish peerage, pervious to the Union, held by an English subject, stood on the same footing as an Irish one at present, he still possessed in England merely the rank of a commoner, and was eligible to being elected a member of parliament. In 1695, Viscount Newhaven was chosen M.P. for Newport in Cornwall, and died 13th July, 1698, in his 74th year. His only son, William, second Viscount Newhaven, was M.P. first for Buckinghamshire and afterwards for Agmondisham till the Union of 1707, when he became a peer of the realm. In 1712 he was appointed lord-lieutenant of Buckinghamshire, but removed from that office on the accession of George I. in 1714. He died 14th December 1738, in his 82d year, without issue, when the peerage, being to the heirs male of the body of the first viscount, became extinct.
