What the name might mean
The leap
Léim Uí Bhriain translates as O'Brien's leap. The leap itself does not appear in any reliable written source — no chronicle, no surviving bardic poem, no land record we have been able to find. Local lore offers candidates: an O'Brien on horseback escaping pursuers across a stream, a chase through the Comeragh foothills, the usual furniture of a placename story. Treat them all as folk explanation rather than fact. The name is older than the records that survive.
Why drivers turn left here
The gateway to the Comeraghs
The R676 north out of Lemybrien is the official start of the Comeragh Drive — a signed scenic loop that takes you up to Mahon Falls and across the back of the mountains before dropping you into Dungarvan. The drive uses Lemybrien because the junction is the easiest place on the N25 to peel off. Most cars pulled in at the petrol station are doing exactly that — coffee, fuel, then up into the hills.
The pitch is here, the parish is over the hill
Kilrossanty GAA
Kilrossanty GAA — one of the older clubs in Waterford, senior football since 1937 — plays its home games at Páirc Naomh Bríd in Lemybrien, even though the parish church and the village of Kilrossanty itself sit a few kilometres north over the foothills. On a Sunday in summer, the cars parked along the verge of the N25 are mostly here for a match nobody driving past on the way to Cork would know was on.
