The names Gurkin, Durkin, Durcan and Dorcan in Ireland are all derived from the native Gaelic O'Duarcain and MacDuarcain Septs that were located in Connaught Province in the West of the country and especially in County Sligo. Gurkan is another variant sometimes used as an anglicized form of these Sept names.

Origen: Irlandés. The Durkan surname is an Anglicized form of the Gaelic Mac Duarcáin. First found in north Connacht, where they were anciently seated 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.
