Translation according to P. W. Joyce:
Ballylin in Donegal, King's Co., Limerick, and Galway, Ballyline in Clare, Kilkenny, and Kerry, and Ballyling in Carlow and Cork; Baile-Ui-Fhloinn [-lin], town of O'Flynn. Initial F dropped out (p. 2, IV) [reproduced below]. N.B. — Irish nn often gets the sound of English ng.
IV. F aspirated loses its sound altogether and drops out. Barranarran, in Mayo, represents the Irish Barr-an-fhearainn, the top or highest part (barr) of the fearann or land, where f vanishes.
