The name was originally Ua Maol Dhómhnaigh in
Irish, which denotes descent from a servant of the Church. The family
originated within the Ui Toirdealbhaigh of the Dál gCais (dahl gash)
contred (now called Dalcassian) of the ancient Irish kingdom of Tuath
Mhuman (tu-ah umon) or Thomond (usually ruled by the Ó Brien Sliocht.
The old Sliocht seat was Cuitenan (Kiltanon), near Tulla, in east
County Clare, where they are very numerous today; though they are also
found in equal numbers in the adjoining counties of Limerick and Tipperary.
