Families covered: O'Conor Don of Ballintober, O'Conor of Connaught, O'Conor Roe

                               
Teige ('of the Three Towers'), King of Connaught (d 954)
BLGI1912 reports of this family that "No family in Ireland claims greater antiquity and no family in Europe, royal or noble, can trace its descent through so many generations of legitimate ancestors." BIFR1976 identifies Teige's son Concover/Conor as "said to be 18th in descent from Daagh Galach, the first Christian King of Connaught, who d AD438". The continuation provides a descent from that Daagh (or Duagh).

BLGI1912 (O'Connor-Henchy of Stonebrook) identifies her as Dervorghil (dau of Felim Finn O'Conor Roe) but that appears to be a duplication for Carbery's mother.
