Aed, Aeddon, Aodh, Aedhan, were far more popular names than those derived from Hu... and two Aoidhs reigned, the one in Connaught, the other in Scotland, in 570; and to the latter of these, called by Scottish historians Aidan, or Edan, they ascribe the foundation of their capital; but it was at that time in the possession of the Angles, and if called after any Aodh, it must have been after an earlier one.  The Irish Aodh is said to have been about to expel the bards, but to have been prevented by the intercession of St. Columb.
... The MacAodhas of Ireland were once many in number; and became MacHugh or Magee; in Scotland, Mackay; or were sometimes translated into Hughson or Hewson.  But the most interesting person so called is known to us as Aidan. (History of Christian Names, Yonge, 1884)
