 The Manx MacCotters are said to descend from a brother of Óttar of Dublin named Acon or Haro (presumably the Norse name Hakon or similar was intended), who was born on the island.Following the Norman invasion of Ireland, the remaining Norse-Gaelic, also known as 'Ostmen,' families of Ireland were in extremely desperate circumstances as they did not have the countryside available to them to the same degree as the Gaelic Irish.This lack of a hinterland to withdraw into forced the Ostmen to fully accommodate the new Anglo-Norman power.
