Maurice FitzGerald, Lord of Llanstephan

Maurice FitzGerald (c. 1105–1176), Lord of Llanstephan in Wales, was a Cambro-Norman baron and a leader of the Norman invasion of Ireland. He fought at the Battle of Crug Mawr in 1136, and in 1146 lost Llansteffan Castle to the Welsh.

In 1169 he sailed to Ireland to back the exiled Leinster king Diarmait Mac Murchada, helping take Wexford and fighting in the storming of Dublin in 1171. He died around September 1176; his sons Thomas and Gerald founded the FitzGerald Desmond and Kildare lines.
