The _Cuilean_ or Cullen from whom this tribe took their name is found in the pedigree of Mac Namara, within the authentic period of Irish history, for he flourished in the eighth century, a period to which our authentic annals reach with perfect historical certainty. Let us then see how this meaning “children of the corner of the water” is obtained from the compound _clann Cuileain_. Apparently by a very simple process, thus; _clann_ means descendants, _cuil_ means _corner_, and _ean_ water; but regular as this process appears, it is nevertheless utterly fallacious, for the word _clann_ means children or descendants relatively to an ancestor, not to a _locality_; and though the name _Cuileain_ (now anglicised Cullen or Collins) when cut in two, would apparently make the words _cuil_ and _ean_, still the word is not compounded of _cuil_, a corner, and _ean_, water, for the first syllable is short, and the last syllable is a diminutive termination of the same power with the Latin _ulus_, as in the compounds _campulus_, _colliculus_, _catulus_; and the word _cuilean_, whether taken as a common noun substantive or as a proper name, is synonymous with the Latin _catulus_, or _Catullus_. The next assertion above made, that _clann Cuileain_ was also called _Hy na mor_, is untrue, for the name _Hy na mor_ had never any existence except in Mr Beauford’s fancy; and even if it had, the meaning given for it would not be correct, for _hy_ does not properly mean district, nor does _mor_ mean sea. The assertion that the chiefs of _clann Cuileain_ were called _Mac na mor aois_ is also untrue, for the name was never so written by any one except Mr Beauford. They were uniformly called _Mic Conmara_, as being the descendants of _Cu-mara_, who was chief of the _clann Cuileain_ in the tenth century; and the name _Cumara_, signifying _hero of the sea_, was first given to a chief of this family, from his being an expert seaman, not from his dwelling on the sea, for the _clann Cuileain_ or Mac Namaras were not located on the sea, or near the sea, but in an inland territory in the south-east of the county of Clare. 2. “CINEAL EOGHEAN, or _Cean all Eoghain_, from _cean thuath oll Eogh-an_, pronounced Connal Owen, or the principal division of the northern county of the Oll or Bolgæ, an ancient district in the province of Ulster, comprehending originally the present counties of Tyrone, Armagh, Donegal, and part of the county of Derry, being the ancient divisions of Eirgal or Orgall,” &c.
