Background
Dub Lemna was a daughter of Tighearnáin mac Seallachan, King of Brefine (died c. 888). Her brother, Ruarc mac Tighearnáin (fl. c. 893), was the eponym and ancestor of the clan Ó Ruairc, Kings of Breifne.
Marriage and children
Dub Lemna married Donnchad Donn of the Clann Cholmáin, who was King of Mide and High King of Ireland from 919 till his death in 944. She was his third wife. Her children by Donnchad are uncertain but they do not include Oengus mac Donnchada, who appears to have been a son of Cainnech ingen Canannán of Ailech, who died in 929.
This leaves sons Conn (died 944) and Domnall Donn (died 952), daughters Flann ingen Donnchad Donn (died 940) and Óebfhinn ingen Donnchad Donn
