The house, a 6,170-square-foot (573 m2), horseshoe-shaped, rustic villa and cottage ornée, was built near Castlewellan in the late eighteenth century.
It lies on some land conveniently halfway between Theodosia Clanwilliam's mother's famous new house at Castle Ward, near Strangford Lough (the mother had married Bernard Ward after the early death of Robert Hawkins-Magill), the seventeenth century holdings of Alderman William Hawkins in and near Rathfriland, the infamous and similarly ancient Magill ancestral seat at Gill Hall, near Dromore, and the Greenore ferry which was caught by way of Newry, which at one time was plague ridden, avoidance of which is said to have been the incentive to build, in six weeks, the house by the Burren.
In 1808 he had married (20.6.1808) Anne Louise (d.1853), daughter and heir of the late General Sir John Dalling, 1st Bt., sometime Governor of Jamaica and later Commander in Chief at Madras.
They had Robert (1809-); Theodosia (*27.1.1811-); John (*23.2.1812-); Louise; Anne; Catherine; Adelaide (*17.2.1818-), who married William Brownlow Forde (1823-1902), PC, MP, DL, JP, of Seaforde, in 1855; Rose (*8.1819-) and Caroline.
