LENOX or DUNBARTONSHIRE, a county of Scotland. See DUNBARTONSHIRE. Among the rivers of this county is the Blane, which, though itself an inconsiderable stream, has been rendered famous by the birth of George Buchanan, the celebrated Latin poet and historian. The same part of the country gave birth to the great mathematician and naturalist, Baron Napier of Merchiston, inventor of the logarithms. The title of Lenox, with the property of great part of the shire, was heretofore vested in a branch of the royal family of Stuart, with which it was reunited in the person of King James VI. whose father, Henry Lord Darnley, was son of the duke of Lenox. This prince conferred the title upon his kinsman Esme Stuart, son of John Lord d'Aubigny in France; but his race failing at the death of Charles duke of Lenox and Richmond, and the estate devolving to the crown, King Charles II. conferred both titles on his own natural son by the duchess of Portsmouth; and they are still enjoyed by his posterity. The people of Lenoxshire are chiefly Lowlanders, though in some parts of it divine service is performed in the Erse language.—The most numerous clans in this district are the Macfarlanes, the Colquhouns, and the Buchanans.
