Baron Rossmore

[1] It was created in 1796 for the soldier Robert Cuninghame, with remainder to his wife Elizabeth's nephews Henry Alexander Jones (the son of Theophilus Jones and Anne Murray, eldest sister of Elizabeth; Henry Alexander Jones died childless before his uncle Lord Rossmore) and Warner William Westenra, son of Henry Westenra and Harriet Murray, youngest sister of Elizabeth.

Henry's younger son, the fifth Baron (who succeeded his elder unmarried brother), was Lord Lieutenant of Monaghan from 1897 to 1921.

As of 2021[update] the titles are held by the latter's great-grandson, the eighth Baron, who succeeded his father in that year.

Henry Westenra, father of the second Baron, represented County Monaghan in the Irish Parliament.

The Honourable John Westenra, third son of the second Baron, was Member of Parliament for King's County.
