The Glenn arms were recorded in Ireland, c. 1645.
Arms such as these were typically recorded in Dublin.
Dublin was the seat of government in Ireland and the place where grants were sought and recorded. Families with business at the castle or the courts settled nearby, and settling there put their arms on record.
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.
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.
The surname Glenn originates from the Gaelic word gleann, which translates to a narrow valley. It was traditionally used as a topographic name to describe families who lived near or within these geographical features. By the mid-seventeenth century, the name was firmly established in Ireland, with records confirming that members of the family were living in Dublin by 1645. During this period, Dublin was a bustling center of trade and political activity, and families like the Glenns were often integrated into the urban professional or merchant classes. As the name spread, it became associated with both Irish and Scottish lineages, reflecting the close historical ties and migration patterns between the two regions. Over time, the name evolved from a simple description of a person’s home into a permanent family identity that was passed down through generations.
A valley or a narrow depression between hills.
