Elizabeth Butler, Duchess of Ormond and 2nd Baroness Dingwall (née Preston; 1615–1684) reunited the Ormond estate as her maternal grandfather, Black Tom, 10th Earl of Ormond had it, by marrying James Butler, later Duke of Ormond, her second cousin once removed (see Family tree). She had inherited her share of the Ormond estate through her mother, Elizabeth Preston, who was Black Tom's daughter and only surviving child. Her husband had inherited his share from his grandfather Walter Butler, 11th Earl of Ormond, Black Tom's successor in the earldom. Her share was the bigger one and included Kilkenny Castle.
