Part of the tower house was demolished and replaced by a 4-storied mansion around 1648. Máire accompanied her husband on raids against English settlers. In 1651, he was mortally wounded fighting on the Royalists' side at Inchicronan (Crusheen). Reportedly, immediately after her husband's death, the widow, realizing that the punishment for his rebellion against the English would be the forfeiture of their property, drove to Limerick and offered to marry any Cromwellian officer who would take her hand. (This is refuted in other versions of the story which state that Máire Rúa didn't marry until 1653, two years after Conor's death.)
