title Lord Clermont was used in the Peerage of Scotland), was a francophile with connections in the royal court of France, and it is believed for that reason adopted a French-sounding title, meaning literally "clear mountain", and a common place name in France. Sir Nathaniel Wraxall wrote on this subject as follows in his memoirs: The very title of "Clermont" which he assumed when raised to the peerage — and which might be esteemed fictitious, as no such place I believe existed in Ireland — assimilated him to the blood royal of France; a younger branch of the illustrious line of Condé having been denominated "Comtes de Clermont". Probably he was not oblivious of this fact, in his selection of the title. However, his biographer and kinsman Lord Clermont (d.1887), countered this suggestion and stated: I cannot suppose that Lord Clermont was influenced by any such motive. The name, common among French towns, probably struck him as well-sounding, and he changed the appellation of one of his seats in Ireland to it, calling Reynoldstown "Clermont Park" and afterwards took his title from his residence. The fact of the name of Fortescue being made up of two French words may have suggested the idea of giving a French name to his estate. However the same author had stated previously that the Earl's father, Thomas Fortescue, had purchased an estate near Dromiskin in Ireland, named Randalstown, which he renamed "Clermont Park". Clermont Park is an estate within County Louth and is near to Lurgangreen, Mooretown and Blackrock and Dromiskin. The mansion house was burned down by armed men in February 1923 when owned by Col. Charles Davis Guinness, county representative of the Irish Unionist Alliance, in one of the many politically motivated arson attacks at that period. An Industrial estate known as "Clermont Business Park" now occupies the site. Only the gatehouse survives, next to St Paul's Church, Haynestown. A Neolithic chambered cairn dating from about 4000–3500 BC, survives atop Black Mountain in the Cooley Mountains in County Louth, in which was situated Fortescue's estate, known in native Irish as Carnán Mhaighréid Náir, also known as Black Mountain Chambered Cairn and Clermont Cairn.
