Origin of the Name Glennon
family history was found in the allfamilycrests.com archives.
Over the centuries Surnames developed a wide number of variants. Different spellings of the same name can be traced back to an original root. Additionally when a bearer of a name emigrated it was not uncommon that their original name would be incorrectly transcribed in the record books at their new location. Surnames were also often altered over the years based on how they sounded phonetically and depending on the prevailing political conditions it may have been advantageous to change a name from one language to another.
Variants of the name Glennon
include Glynn, McGlennon, Glenn, McGloin, Maglynn, McGlone, McAloon, Gloon and Monday. This name in Irish is MagFhloinn and the latter variants are the anglicized forms of this. This sept came from the Westmeath and Roscommon area. When Gaelic names were anglicized during the sixteenth and seventeenth centuries they were often changed to Anglo equivalents that sounded most like their original Gaelic name.
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 as North of Donegal. From that area are recorded several priests throughout history in the diocese of Raphoe with one of these being famous in America he being Dr. Edward MacGlynn, 1837-1900. The variant Glynn is more numerous in North Connacht and Glennon in Leinster . McGloin and its other synonyms, McGlone, McAloon, Gloon and Monday, are quite widely found in Counties Fermanagh and Derry.
The Glennon 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 Glennon descendants.
