 Its name comes from the Irish "Abha Bheag" ("small river", a slightly older form than the modern Irish name).There are two contributories of the Awbeg.The first rises in County Limerick as the Gralgne River and enters County Cork a half mile north-east of Ardskeagh Cross Roads, then flows west under a railroad bridge and south under Farran bridge on the Buttevant/Charlevllle road.
