Surname Grehan - Meaning and Origin

all surnames with 'G'

Grehan: What does the surname Grehan mean?

The last name Grehan is of Irish origin and is one of the many Anglicized forms of the Gaelic-Irish surname Ó Gréacháin. The derivation comes from the personal name Gréachán which means 'Little person with rough or severe look'.

The Grehan family were believed to have been descendents of the Heremon dynasty, which was descended from the Gaelic High King Niall of the Nine Hostages and spread across Ireland from the provinces of Connaught and Leinster.

In medieval times, the Grehans held prominent positions as lords, warriors and lords of the manor. They were territorially based in the small villages of Kilmoily and Ballintober, located in the ancient kingdom of Thomond. The family also had impressive strongholds throughout central Ireland and held positions of authority at a number of monasteries and churches.

The family is still known for holding strong traditional values and pride in their Gaelic heritage. Many descendants of the Grehan family still remain in Ireland, although the name is now more commonly found throughout the United States and the Canadian provinces of Ontario and Quebec, where many members of the Grehan family emigrated in search of a new life.
