In reply to the inquiry of "D.S.Y." (p. 158. of your 10th number), I beg
to say that the name of Armagh is written, in Irish, Ardmacha, and
signifies the Height (or high ground) of Macha. It is supposed to have
derived this name from Macha Mong-ruadh [i.e. Macha of the red hair],
who was queen of Ireland, according to the Chronology of O'Flaherty,
A.M. 3603.
