Life

Saint Diarmaid of Gleann Uissen is an Irish saint of the undivided Church, remembered in the old martyrologies of Ireland as a bishop.

The Donegal text places Gleann-⁠Uissen in Ui-⁠Bairrche and says he was of the race of Cathaoir Mor, monarch of Erin, among the Lagenians.

The Martyrology of Donegal, compiled in 1630 from older sources, commemorates him on 8 July. The Martyrology of Tallaght, from the early ninth century, lists a similar name on the same day. The date is that of the old Irish calendar, that is, in the old style.

No further details of his life survive in the sources consulted.
