Translation according to P. W. Joyce:
Ballybanagher in Galway; Baile-beannchaire [-ban-agher], the town of the beanns [banns] or pointed hills. For beannchoir, see Banagher, vol. i. p. 385 [reproduced below].
Beannchar or beannchor [banagher] is a modification of beann, and signifies horns, or pointed hills or rocks, and sometimes simply peaked hill; it is a word of frequent topographical use in different parts of Ireland, and it is generally anglicised banagher or bangor. Banagher in King's County (Beannchor, Four Mast.) is said to have taken its name from the sharp rocks in the Shannon; and there are seven townlands in different counties bearing the same name. Bangor in Down is written Beannchar by various authorities, and Keating and others account for the name by a legend; but the circumstances that there are so many Beannchars in Ireland renders this of no authority; and there is a hill near the town, from which it is more likely that the place received its name. Coolbanagher or Whitechurch, a church giving name to a parish in Queen's County, where Aengus the Culdee began his celebrated Felire (see p. 158), is written in Irish authorities, Cuil-beannchair, the angle or corner of the pinnacle. "There is a Lough Banagher (the lake of the pinnacles) in Donegal; Drumbanagher in Armagh; Movanagher on the Bann, parish of Kilrea, Derry (Magh-bheannchair, the plain of the pinnacles); and the ancient church of Ross-bennchuir (ross, a wood), placed by Archdall in the county of Clare" (Reeves, Ecclesiastical Antiquities, p. 199, where the word beannchar is exhaustively discussed).
