The surname Durcan was first found in north Connacht (Irish: Connachta, (land of the) descendants of Conn), where they held a family seat as Chiefs of their race. Irish history was greatly influenced by the Norman invasion of 1172, and thereafter, the surnames of Irish Gaelic clanns and septs and many of the Norman families became almost indistinguishable. This family name was found later in Sligo where seated and represented the first recorded reference to the name by Sineall, son of Cassan. They were descended through the MacNamara line from the O'Brien Kings of Ireland.
