Uí Maine tuaiscert ocus deiscert
Cairbre Crom's descendant Anmchadh mac Eogan Buac (died c. 757), founded the kingdom of Síol Anmchadha, which was referred to as deiscert O Maine (southern Uí Maine). Families descended from Cairbre via Anmchadh include hUallacháin and Madden.

Eoghan Finn was the ancestor of King Tadhg Mór Ua Cellaigh (died 1014), from whom descend the Clann Ó Cellaigh or Kelly of County Galway, who were referred to as tuaiscert O Maine (northern Uí Maine).

Finn and Buac
The two Eoghan's shared the same name because they likely had different mothers, hence the use of epithets. They were sons of Cormac mac Cairbre Crom.
