The
FitzGerald dynasty is a
Hiberno-Norman or
Cambro-Norman dynasty, and have been
Peers of Ireland since at least the 14th century. The dynasty has also been referred to as
the Geraldines. They were established by the conquest of large swathes of Irish territory by the sons and grandsons of
Gerald FitzWalter of Windsor (c. 1075-1135). Gerald was a Norman
Castellan in Wales, and is the male progenitor of the Fitzgerald dynasty ("fitz", from the Latin "fils" indicating "sons of" Gerald).
