Happy St. Patrick’s Day


This interesting name, with variant spelling O’Casey, is an Anglicized form of the Old Gaelic “O’Cathasaigh”, from the Gaelic prefix “O” indicating “male descendant of”, plus the personal byname “Cathasach”, meaning vigilant or watchful. Traditionally, Irish family names are taken from the heads of tribes, revered elders, or from some illustrious warrior, and are usually prefixed by “O”, as above, or “Mac”, denoting “son of”. Six distinct septs of this name existed in Ireland
