Early Origins of the O'Rogan family

The surname O'Rogan was first found in Armagh (Irish: Ard Mhacha) located in the province of Ulster in present day Northern Ireland, where they held a family seat as chiefs of great importance. In Gaelic, the name was Ó Ruadhagáin and was "an Oriel sept formerly of considerable importance." 1 The name is derived from "ruadh" meaning "red", so the surname can be translated as "red-haired." 2

The family claim descent from the O'Hanlons, Lords of Orior, in the County Armagh and recognize this ancestry through a very similar Coat of Arms. Both have a green shield with a boar on a mound in the base of the shield. Specifically, the family claim descend through "Feig, son of Felim, who had a brother name Eachach, who was the ancestor of Rogan." 3
