Connmach
From BiblePortal Wikipedia
Connmach [1]
(or Conmach), an early Irish prelate, succeeded Cudiniscus as bishop of Armagh some time after A.D. 790 (Four Masters). He died suddenly in 807, and the Psalter of Cashel gives him a rule of fourteen years. Under his influence St. Fothad the Canonist drew up the remonstrance which procured for the clergy of Ireland the right of exemption from military service (Lanigan,,Ecclesiastical History of Ireland, 3:233, 244, 252; Primitive Church History of Ireland. 2:1106).
Of Conmnmach of Ath-blair, commemorated as an Irish saint on July 9, we have no account.
