Gibson's work draws on references such as O'Brien's Corpus Genealogiarum Hiberniae and Byrne's Irish Kings and High-Kings, which outline the genealogical framework of the Eóganacht.

According to Frost, the Uí Cormaic settled in what is now the Islands Barony, possibly on the territory of the Corcu Baiscinn, located directly east of Tulach Commáin.

Gibson suggests that Cahercommane, associated with Tulach Commáin, may have been the centre of a short-lived Eóganacht chiefdom, or part of the larger mór túath (over-kingdom) of the Corcu Mruad.

This connection would place Célechair mac Commáin's lineage within a royal framework, with ancestors likely holding the title of Rí (king) at various levels of the Eóganacht hierarchy.
