Conlan is a surname of Irish origin. In its original Gaelic form it was spelt a number of different ways, resulting in many English-language versions, such as Conlon, Connellan, etc.
The O'Connellans were chiefs of Crioch Tullach, in County Tyrone. O'Conalláin (O'Connellan or O'Kendellan) were princes of Ui Laeghari or "Ive-Leary" in the tenth and eleventh centuries, an extensive territory in the counties of Meath and Westmeath (O'Coindealbhain, O'Connialláin, O'Connolláin, O'Connellan). Branches of this family in the twelfth and thirteenth centuries settled in the counties of Roscommon, Galway and Mayo.
