Question: What is the name of the fourth Marquess of Donegall? Passage:His grandson, the third Marquess, served as Captain of the Yeomen of the Guard under Lord John Russell between 1848 and 1852. In 1841, three years before he succeeded his father in the marquessate, he was created Baron Ennishowen and Carrickfergus, of Ennishowen in the County of Donegal and of Carrickfergus in the County of Antrim, in the Peerage of the United Kingdom. Both his sons predeceased him and on his death in 1883 the barony of 1841 became extinct. He was succeeded in his other titles by his younger brother, the fourth Marquess. On the death of his grandson, the sixth Marquess, in 1975, the line of the second Marquess failed. The sixth Marquess was succeeded by his kinsman, the fifth Baron Templemore (see below), who became the seventh Marquess. From 1975 until 1999, when most hereditary seats were abolished with the passage of the House of Lords Act 1999, the Marquess sat in the House of Lords as Baron Fisherwick in the Peerage of Great Britain. , the titles are held by the latter's son, the eighth Marquess, who succeeded in 2007.
