Elizabeth Calf

Elizabeth le Veel, also known as Elizabeth Calf, was an AngloIrish noblewoman, and wife of Art mac Art MacMurroughKavanagh, King of Leinster. Her marriage to Art violated the Statutes of Kilkenny, and resulted in her property being forfeited to the English crown. This caused her husband to declare war in Ireland against the forces of King Richard II of England.

Elizabeth was born at Norragh, County Kildare, Ireland on an unknown date, the daughter and heiress of Sir Robert le Veel of Norragh. Norragh had been in her family since the manors of Norragh and Skethness, were granted to her ancestor Sir Michael le Veel in 1320. Her family is better known by the name Calf, which is the Anglicised version of le Veel.
