Meaning & Story
An Irish surname meaning 'son of the servant of Jesus,' from Gaelic 'Mac Giolla Íosa.'
Gleeson carries Irish heritage and Hollywood charm — Brendan and Domhnall Gleeson have brought the surname into the international spotlight through their celebrated film careers. As a pet name, it's warm, distinguished, and a little bit literary. Perfect for a friendly male dog with a kind face — a Wheaten Terrier, an Irish Setter, or any breed with serious Celtic charisma.
