Beannchar, ‘perhaps meaning 'place of points'
Quite a few townlands in various parts of Ireland have been anglicised as Banagher and derive from an original Beannchar. Yet Beannchar in North Down was anglicised as Bangor. It may have been influenced by the name Bangor which is commonly used as the name of ecclesiastical sites in Wales. Beannchar here could have initially referred to a fence round the monastery.
From Conchobhar meaning ‘dog lover’. The name has been in use in Ireland for many centuries.
