Mo Bí Cláirenach m. Comgaill of Inch

Other names

Dabiú m. Comgaill (Rec. Mai 152). Bíthe of Inch, Mo Bíu, David (Ó Riain, Dictionary, 106), Biteus.


Thomas Charles-Edwards considers that the cult of this saint was strong enough by at least the second half of the seventh century to motivate the supporters of a rival saint - St Dichu - to create a story, now embedded in the Patrician tradition, discrediting Mobi's family, the Dál mBuain. Dichu and Mobi had rival churches, both near the royal centre of Downpatrick in Co. Down (Charles-Edwards 2000 p 64-7). Mochua m. Beccáin, another saint connected with the Dál mBuain, has a Life which claims a Da-Biu was born to a barren woman through Mochua's tears (Stokes 1890 p 282). Forbes considered that some dedications and fairs - Feill Dáidh and Cill Dáidh in Weem and a church dedicated to Movean in Kippen, Stirlingshire - were attributable to a St Dabius of 22nd July (Forbes, Kalendars, 320), but the Weem fair was in March (NSA, Perth p 705). None of the mart. entries have patronymic. Association with Inis Cuscraid begins with Mart O. All genealogies descend a Mobí or Dobiú m. Comgaill from Eochu m. Maireda or assign him to the Dál mBuain. The conjunction of patronymic, descent from Eochu m. Maireda, and connection with Inis Cuscraid is only in Mart Do.

Dobiu m. Comgaill m. Eirc m. Araide m. Coluimb m. Cainnig m. Buain, followed, in RB 502 and BLec by ‘a quo Dál Buain’ (Rec. Mai,152). Rec. min. and Rec. met. have descent from Eochu m. Maireda (CGSH no 446, 662.185). The Dál mBuain may have been a branch of the Ulaid (Ó Riain, Dictionary, 106), but they seem to have been base clients of the Dál nAraide (Charles-Edwards 2000, 61-65)
