Fitzgerald Family History
Fitzgerald Name Meaning
Irish: from Anglo-Norman French fi(t)z ‘son’ (see Fitz ) + the personal name Gerald (see Gerald ) ‘son of Gerald’. This is a very common Anglo-Norman name in Ireland where it has been Gaelicized as Mac Gearailt. Irish bearers of the name claim descent from Gerald Fitzwalter de Windsor constable of Pembroke Castle in the early 12th century whose grandson Raymond (or Redmond) ‘le Gros’ FitzGerald (died after 1185) led the invasion of Ireland on behalf of Strongbow in 1170. A branch of the family held the title Knight of Glin from at least 1299–201
