Notes
[1] MacAodh: For the derivation of this sirname see the "Hughes" pedigree. In the transition of the Irish sirnames from the Irish to the English language, the name Aodh was by the English sometimes pronounce "Od:" hence MacAodh was anglicised Odson, and in the course of time, Hodson and Hudson; each meaning the sons or descendants of Aodh.
[2] Hewson: This name has been rendered Hewston and Houston.
