Where the Grehan Arms Were Recorded

Map of Ireland showing where the Grehan arms are recorded

The Grehan 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.

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.

Origin & History of the Grehan Family in Ireland

The family name Grehan is rooted in the Gaelic tradition of Ireland, specifically originating from the Irish surname Ó Greacháin. Historically, this name is most strongly associated with the province of Connacht, though members of the family established a notable presence in Dublin by 1645. During the seventeenth century, Dublin served as a center for political and social transition, and the presence of the Grehan family there suggests they were part of the urban migration that brought rural Gaelic families into the capital. As the name evolved over time, it shifted from its original Irish form into the Anglicized version used today. The family likely navigated the complex social changes of the era by maintaining their identity while adapting to the growing influence of English administration in the city.
