GLEESON Family History

This is an anglicized form of the Olde Gaelic O' Glasain or O' Gliasain. The Gaelic prefix "O" indicates "male descendant of", plus the personal byname Glasain, from "glas" literally meaning "green", but used here in the sense of inexperienced. This sept belonged to the ancient territory of Mac Ui Bhriain Aradh's country, that is the area between Nenagh and Lough Derg on the border of North County Tipperary. The Gleesons were of the same stock as the O'Donegans, whose name derives from the Gaelic 'donn' meaning brown or dark.

Eileen Gleeson

My father Thomas Gleeson was born in Limerick Ireland about 1923 and came to the US, Chicago area, in 1948. He married Beatrice Clinnin in 1952. His brothers Michael, Owen, Timothy and John also moved to Chicago. A sister Nellie (Eileen) stayed in Ireland and married a McGrath. The oldest brother Philip never married and never left the farm in Limerick. I have one sister Kathleen and my brother James who died in December 2017.
