AN elderly brother and sister died when a fire engulfed their two-storey farmhouse outside Killarney, Co Kerry, on Saturday. John and Julie-Anne O'Callaghan, both in their 80s, lived at Knockdoorah, Barraduff. Their brother, Jeremiah, in his late 70s, saw flames from a nearby field, but was unable get in. It is believed the fire was accidental.
