Who they were
Sineach, daughter of Fergna, of Cruachan Magh-Abhna, in Caenraighe. She was of the race of Eoghan Mor, son of Oilioll Olum, according to the Naomh-Senchas.
The miracles
There was never a formal cause: she has been honoured as a saint since before the Church's formal processes began.
Why that counted as sanctity
The Martyrology of Donegal remembers her on 5 October.
