The O'TOMHRAIRs, it is said, took their family name from TOMAR, a Danish king of Dublin. Strange...since the first reference to the family (c1300) is in County Donegal, Ireland near Lifford (as far from Dublin as you can get). They were affiliated with the Cenel Eoghan (O'Neills). The name moved through Countys Derry, and Tyrone and into Armagh. From there members spread to larger Irish cities and the world.
