Sir John Boswell, of Balmuto, was succeeded by his son David, who married first Elizabeth, daughter of Sir John Melville, of Raith, and secondly, Isabel, daughter of Sir Thomas Wemyss, of Rires, relict of David Hay, of Naughton. Robert, younger son by the first marriage, became parson of Auchterderran, and was much esteemed for his piety and learning: he attained his hundredth year. David, the elder son, obtained, in 1458, from James II., by a charter under the great seal, the lands of Glasmont, in Fife. He married first Grizel, daughter of Sir John Wemyss of that ilk; and secondly, in 1430, Lady Margaret Sinclair, daughter of William, Earl of Orkney and Caithness. Thomas, eldest son of the second marriage, obtained from James IV., as a signal mark of royal favour, the estate of Auchinleck,[3] in Ayrshire. He was slain at Flodden on the 9th September, 1513. By his wife Annabella, daughter of Sir Hugh Campbell, of Loudoun, he had an only son David, who, succeeding to the paternal estate, espoused Lady Janet Hamilton, daughter of James, first Earl of Arran. David was succeeded by his son John, whose first wife was Christian, daughter of Sir Robert Dalzell, of Glenae, progenitor of the Earls of Carnwath. Of this marriage, James, the eldest son, succeeded to Auchinleck. He died in 1618, leaving by his wife, Marion Crawford, of Kerse, six sons, three of whom entered the service of Gustavus Adolphus, and ultimately settled in Sweden. David Boswell, the eldest, succeeded to Auchinleck; he was an ardent supporter of Charles I., and was fined ten thousand marks for refusing to subscribe the Covenant. He married Isabel, daughter of Sir John Wallace, of Cairnhill, but having no male issue, he was at his death in 1661 succeeded by his nephew David, son of his next brother James by his wife, a daughter of Sir James Cunninghame, of Glengarnock. David Boswell of Auchinleck espoused Anne, daughter of James Hamilton of Dalziel, by whom, besides three daughters, he had two sons, James and Robert. The latter settled in Edinburgh as a Writer to the Signet, and acquiring a handsome fortune, purchased from his kinsman, Andrew Boswell, the estate of Balmuto, which had belonged to his ancestors. His son, Claude James Boswell, born in 1742, passed advocate in 1766, and after serving eighteen years as sheriff of Fife, was in 1798 raised to the bench, under the judicial title of Lord Balmuto.[4] His lordship died on the 22nd July, 1824.
