Origin of the Name McGleenan
The origin of the name
McGleenan was found in the allfamilycrests.com archives. Variants of McGleenan include McGlynn McGlennon, Glennon, Glenn, McGloin, Maglynn, McGlone, McAloon, Gloon and MacAleenan. This name in Irish is Mag Fhloinn and Mac Giolla Fhinein and the latter variants are the anglicized forms of these names. This sept came from the Westmeath-Roscommon area.
A sept or clan is a collective term describing a group of persons whose immediate ancestors bore a common surname and inhabited the same territory. Irish septs and clans that are related often belong to even larger groups, sometimes called tribes.
They spread to the Shannon and even as far North as Donegal. In that area we find several priests of the name throughout history in the diocese of Raphoe and one of these was famous in America, he being Dr. Edward MacGlynn, 1837-1900. The variant Glynn is more numerous in Connacht and Glennon in Leinster . McGloin and its synonyms are quite widely found in Counties Fermanagh and Derry. McGleenan is today mostly found in County Armagh.
The McGleenan coat of arms came into existence centuries ago. The process of creating coats of arms (also often called family crests) began in the eleventh century although a form of Proto-Heraldry may have existed in some countries prior to this. The new art of Heraldry made it possible for families and even individual family members to have their very own coat of arms, including all McGleenan descendants.
