FITZGERALD

The family of Fitzgerald was an Irish family descended from William, Castellan of Windsor in William the Conqueror's reign. Two branches of this house, the Earls of Desmond and Kildare, were for a long while the practical rulers of the English part of Ireland. The Kildare branch is still represented by the ducal house of Leinster.
