husband to become a Roman Catholic, she herself having returned to her own faith soon after her marriage. She was the mother of Mary Villiers, Duchess of Richmond and of George Villiers, 2nd Duke of Buckingham (who inherited her title as 20th Baron de Ros). Katherine's first husband, Buckingham, was murdered in 1628 by John Felton. Upon the death of her father in 1632, without male heirs, she succeeded suo jure to the ancient barony of de Ros. In 1635 she married Randal McDonnell, Earl of Antrim, and went to live at Dunluce Castle, County Antrim, Ireland. Following the Catholic uprising in Ulster in 1641 the MacDonnell family moved south to Wexford, then Waterford, where Katherine died in 1649. She was buried outside the walls of Waterford and it is speculated that she may have been a victim of the plague. Her possessions passed to her son and a memorial was erected in Westminster Abbey.
