EARLS OF SELKIRK, FORFAR, AND DUMBARTON; VISCOUNT BELIIAVEN, AND LORDS MORDINGTON.—In 1646, the third son of the first marquis of Douglas was created earl of Selkirk. In 1651, the eldest son of the same marquis was created earl of Ormond, and in 1661, earl of Forfar. In 1675, the fourth son of the same marquis was created earl of Dumbarton. In 1641, the second son of the tenth earl of Angus was created lord Mordington. In 1633, sir Robert Douglas of Spot, a descendant of the Morton family, was created viscount of Belhaven. Of all these titles, that of the earl of Sel kirk is the only one not now dormant or extinct.
A History of the Houses of Douglas and Angus, by David Hume of Godscroft, was published at Edinburgh in 1644, in 1 vol. fol., and reprinted in 1748 in 2 vols. 8vo. It preserves the traditions of the family, and has some literary merit, but its accuracy is not to be trusted. The earlier history of the Douglases has been critically examined by
the late George Chalmers in his Caledonia, vol. i. pp. 579-84 (Lond. 1807); by Mr. Rid dell in his Remarks upon Scotch Peerage Law, pp. 174-78 (Edin. 1833); by Mr. Cosmo Innes, in the Registrum Episcopatus 3foraviensis, pp. xliv.–xlvii. (Edin. 1837); and the Tiber S. Marie de Calcium, vol. i. pp. xxvii., xxviii. (Ellin. 1846); and by Mr. Joseph Robertson in the Origins Paroehiales Scotice, vol. i. pp. 152-60 (Edin. 1851). The descent of the houses of Angus and Dalkeith was first ascertained by Mr. Riddell in his Remarks upon Scotch, Peerage Law, pp: 154-64 (Edin., 1833); and in his Stewartiana, pp. 82-4, 137-42. The dialler's and cOlTeSriondenee of the Morton family have been edited for the Bannatyne club by Mr. Cosmo Innes in the Registrum Honoris de Morton (Edin., 1853, 2 vols. 4to).
