Síl Muiredaig Genealogies
Here I have tabulated the genealogies of the Síl Muiredaig down to the late twelfth century as given in the Book of Ballymote, with a few additions from MacFirbis, O’Clery, & An Leabhar Donn, along with whatever titles and obits or additional persons may be found in the various annals (chiefly the Annals of Ulster, Inisfallen, Tigernach, and the Four Masters) or in the notes within the genealogies themselves, and indications of the extractions of later families.
For those who cannot wait for Jaski's edition of the genealogies to be published on CELT, I have my own transcript of the BB version, which I can make available by request.
