 One early item of genealogical information, which specifically identifies the Mac Léníni and Mac Duinich as sub-branches of the Rothrige (though it does not name Colmán), achieves this by making their eponymous progenitor Eochaid Rothán a son of the Éoganacht ancestor Mug Nuadat.The saint's genealogies later come to trace Colmán's ancestry to Mug Nuadat through seven generations.This prominence accorded to the Éoganachta in the genealogies is to be seen in the light of Colmán's monastic career and the position of Cloyne after his death (see below).
