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

English translation
(last line at bottom)
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 today is located on the eastern seacoast of County Cork near the seaside resort 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."
