Note 28 — Chapter XIII
Reading edition
In the "Martyrology of Tallaght" this curious name is written Mac hui Machteni, i.e., the son of the grandson of Machtenus, or Muirchu, i.e., Murrough, descendant of Machtenus, and the Leabhar Breac has this note at the name of Muirchu: "civitas ejus in uib Foelan, i.e., mac hui Mathcene," thereby giving us to understand that he was a native of what is the present county of Waterford. Maccumachteni is not a surname, for these were not introduced into Ireland for three centuries later.
