Biography
What little is now known about Muirisc can be traced to two short medieval poetic references.Muirisc was given rule by her father, Úgaine Mór, the sixty-sixth high king of Ireland who is said to have divided Ireland into twenty-five shares, one for each of his children. Her siblings included Lóegaire Lorc, Cobthach Cóel Breg, as well as a sister named Lathar.
Muirisc placed her stronghold near Clew Bay in the shadow of Cruachan Aigli, now known as Croagh Patrick. She was known as a sea captain and a warrior who "ruled o'er hardy sailors and great men" and was famed as much for being "daring" and "bold" as she was for her beauty and "snowy hands."
