FitzGerald dynasty
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 French "fils" indicating "sons of" Gerald).
