The Kirwan were the only family amongst the Tribes of Galway
to establish an Irish origin, tracing a descent from the
second son of Milesius, one of the original Gaels. They left
many fine castles, including Cregg Castle, Castlehackett,

They appear to have settled in Galway, in
the reign of Henry VI. about which time, the name first

William Kirwan and his children. Some think they are much more
ancient, supposing them to be the family of Kirwicke,

town. This supposition is very probable, as the
orthography of the name has undergone various changes, viz. O'Quirivan, Kyrvan, Kerovan, Kirevane, but it is now

To this name and family, Ireland
is indebted for two individuals, of the first order of
genius, men whose splendid talents have raised their native
country to a most elevated point in the scale of literature
and science. By those the reader may easily anticipate, are
meant the celebrated Dean Kirwan, and his distinguished
relative and friend, the late Richard Kirwan, Esq. of Cregg.
The former, acknowledged to have been the first Christian
orator of his day, and the latter, one of the greatest
philosophers of the age in which he lived.
The families of Blindwell, Castlehackett, Cregg, Gardenfield, Glan, Hillsbrook and Woodfield,
in County Galway; and Dalgin, in County Mayo,
are the principal of the name.
