The pipe roll of Cloyne contains a collection of muniments relating to the see of Cloyne. It was originally composed c.1364 and contains material spanning the period c.1216 to 1489. This edition reproduces with some emendments the earliest published version - the original was destroyed - and adds an English translation. The second half of the book consists of extensive annotated references which, as well as dealing with all technical or subject issues raised, fully treats of all families ocurring in the source. As many of these were major families with lands elsewhere in Ireland this study represents a major source for the families of the Anglo-Norman period in Ireland.
