The Mermaid’s Tale
Local legend tells of a wine-loving mermaid who inhabited the tranquil waters of Killone Lake, slipping through an underground passage to indulge in the wine of the O’Brien cellars. Confronted, she fled wounded to the depths — but not without a curse upon the family: “As the mermaid moves on the sea, so shall the O’Briens fade away from this land until Killone is overgrown with wild weeds.” They say that every seven years the lake’s waters turn red in remembrance.
The O’Briens have long since passed from Killone — yet the tale endures as a cherished piece of folklore, weaving an air of mystique around lake and house alike. Beside the water stand a 12th-century abbey and the Holy Well of St John the Baptist, where pilgrims still gather each June; and at Newhall, the mermaid is honoured on the very arms of Clan Ó Comáin, its custodians today.
