Cambro-Normans were Normans who settled in southern Wales after the Norman conquest of England in 1066. Some historians prefer this term over Anglo-Norman for the Normans who invaded Ireland after 1170 since many of them originated in Wales. Contemporary Irish accounts of this period simply called the incomers Saxain, which means "Saxon", i.e., "English".
In addition to such Cambro-Norman lords, some of Ireland's most prominent families, including Walsh, Butler, Joyce and Griffith, were indigenous Welsh families who came with the Norman invasion. (The surname "Walsh" itself, or in Irish Breathnach, "Briton", means "Welshman", and was applied by the Irish to Welsh who didn't have a surname). Other indigenous Welsh surnames such as Taaffe which came at this time became very important families within the Pale community.
