Annals of the Four Masters
Under the year 1581, the Annals of the Four Masters relate the story of Burke:
The son of the Earl of Clanrickard, i.e. William Burke, son of Rickard Saxonagh, son of Ulick-na-gCeann, son of Rickard, son of Ulick of Cnoc-Tuagh, was hanged at Galway, the third day after the execution of Turlough O'Brien; that is, Turlough was hanged on Thursday, and William on Saturday. It happened that William was joined with his relatives in the war when they demolished their castles, as we have already mentioned; that he grew sorry for this, and went to Galway, under the protection of the English, the month before his execution; but some tale was fabricated against him, for which he was taken and hanged. Such of his followers as went in under this protection were also hanged.
