- The families of Hugh O'Beirne and Patrick O'Beirne were both descended from Teige O'Beirne resident in the Drumsna area in the early 18th century. These two branches of the O'Beirne family were living at Jamestown and Dangan (the original O'Beirne stronghold) in the early 19th century. Patrick O'Beirne was a son of Colonel Andrew O'Beirne, Chief of the O'Beirne clan in the late 18th century. Andrew lost most of his property after the 1798 rebellion and four of his sons emigrated from Ireland. Patrick remained at Dangan and O'Beirnes continued to live there until at least the late 1830s.
- Melvin writes that this was a wealthy branch of the Browne family. Catherine daughter of Martin Browne of Cloonfad, county Roscommon married Denis O'Conor of Bellanagare and they were the parents of the antiquarian Charles O'Conor (1764-1828). Martin Browne's other daughter with a dowry of £2,500 married Thomas Lynch of Lowberry in 1782. By the time of Griffith's Valuation Mrs Margaret Browne retained 66 acres at Cloonfad More and a house valued at £4. The Brownes held Cloonfad from the Mahons of Strokestown. Father Martin Coen indicates that George Joseph Plunkett Browne was a member of this family. He was born in 1795 and was Bishop of Galway and subsequently of Elphin in the 1830s and 1840s .
