In Ireland, the name Gleason is found throughout the province of Munster and is derived from the original surname Glaisine, pronounced "GLASH-inn-eh." The Fragmentary Annals of Ireland, written by Christian monks in the early half of the 11th century, records the tribal king's death in 906 AD - at the height of the Viking Age.
"AD 906 The death of Glaisine son of Uisine, King of Ui Meic-Caille."

Also celebrated by the 15th century bard O'Heerin, Glaisine is described as "a chief of "Ui Meic-Caille" who co-ruled the barony of Imokilly, which is located on the eastern seacoast of County Cork near the modern day town of Youghal (pronounced "Yall.")

"A valiant clan, warlike in pursuit,
Ruled Imokilly of the hospitable banquets
two tribes possessed the smooth plains
O'Bregan and the fair O'Glasin."
