Book of Hy-Maine
The Book of Hy-Maine, generally called the “Book of the O’Kellys,” was compiled partly by the O’Dugans, the hereditary bards and historians to the O’Kellys; and partly by Faolan Mac an Gobhan (or Smith), a learned historian, who is mentioned in O’Reilly’s Irish Writers, at A.D. 1423. This Book of Hy-Maine is a voluminous MS., on vellum, containing a vast deal of curious and interesting information on the history and antiquities of Ireland.
