About Downey

Downey is an Irish surname that means in English “belonging to a fort”. The name is found from ancient times in areas of Ireland's modern County Galway, southwest Cork, Kerry, Limerick, Ulster and Leinster and is believed to be the surname of three distinct families. In Ulster, Downey were the chiefs of the Ulaid petty-kingdom of Cinel Amhalgaidh, now known in the Anglicised form as Clanawley in County Down.
