Ballyrogan, County Down


Ir. Baile Uí Ruagáin ‘O’Rogan’s townland’


The second element of Ballyrogan is the surname Ó Ruagáin (earlier Ó Ruadhagáin), Ruagán meaning ‘little red-haired one’.  According to Woulfe (1923, 635), this is an Oriel surname whose bearers were one time rulers of Eathach which was coterminous with the present-day barony of Armagh.  O’Rogan was one of the most common surnames in the Co. Down baronies of Kinelarty and Dufferin in the second half of the 17th century (Census 86).  The suffix -loughmaroony, which appears in the spelling Ballyrogganloughmaroony in 1675, no doubt refers to a lough which has since dried up or been drained; this must have been beyond the current townland boundary as Ballyrogan is mainly hilly ground. A possibility is Kiltonga Lake in the neighbouring townland of Milecross. There is a townland named Ballyrogan in the parish of Kilkeel, Co. Down and another in the parish of Errigal in Co. Derry.
