The following genealogy is taken from a text within the O Clery Book of Genealogies [1] a genealogical collection compiled in the seventeenth century. The names of most of those appearing in the terminal generations have been omitted for reasons of clarity. The numbers in square brackets are the paragraph numbers in the published edition. Names have been standardised. It has not been possible to determine where the line in paragraph 311 fits into the wider genealogy. for more click here
