The Expulsion of the Dessi (Author: Unknown)
paragraph 7
There chanced to be a famous warrior with the Hui Bairrchi, to wit, Eochu Guinech, son of Oengus, and he it was who drove them out of their land. Then Crimthann, son of Enna, sent the wandering host of the Dessi to Ard Ladrann southward, whence the Land of the Wandering Host and the Folk of the Wandering Host have been so called ever since.
