Mayo
Map of Ireland showing where the Glennon arms are recorded
The Glennon arms were recorded in Mayo, c. 1645.
Mayo was poor western Irish country of bog and mountain, held by a small number of old families. Land changed hands rarely there, and families who held on appear in the records.
This is where the arms were entered in the register. Families often moved to other parts of the country, so the same name can turn up in more than one region.

How Arms Worked in Ireland
The Ulster King of Arms granted coats of arms to individuals who proved their social standing and good character. These symbols were typically inherited by all legitimate descendants of the original holder. If a family branch wanted a unique look, they could apply for a specific change to their design through the office to ensure their identity remained distinct.
Granting authority
The Ulster King of Arms acted as the official body that regulated and issued all coats of arms throughout Ireland.
How they got arms
Families obtained their arms through formal grants issued by the office after proving their eligibility and paying the required fees.
Where arms were recorded
All official grants were recorded in the registers held by the Ulster King of Arms starting from the year 1552.

Origin & History of the Glennon Family in Ireland
The family name Glennon is primarily associated with the province of Connacht in western Ireland, where it has deep roots in County Mayo. By the year 1645, records confirm that members of the family were well-established in this region, living during a period of significant political and social upheaval. The name itself is an anglicized version of the Gaelic surname *Ó Gleannáin*, which translates to descendant of the follower of the devout one. Historically, the family belonged to the Gaelic social order, existing within the complex clan systems that defined rural life in Ireland before the widespread changes of the seventeenth century. As farmers and local community members, the early Glennons navigated the challenges of land ownership and shifting loyalties during the mid-1600s, maintaining their presence in the rugged landscape of Mayo despite the pressures of the era.
