The Chief Irish Families of
Munster
The following is a brief summary of the Irish families
in Munster, beginning with the three branches of the race of Heber:
namely, the Dalcassians, the Eugenians, and the Clan Cian.
I. The Dalcassians: According to
Connellan, the chief families of this sept were - Lysacht, MacArthur,
MacBruodin, MacClancy, MacConry, MacCurtin, MacDonnell, MacEniry,
MacGrath, MacMahon, MacNamara, O'Ahern, O'Brien, O'Brody, O'Casey,
O'Cashin, O'Considine, O'Davoran, O'Dea, O'Duhig, O'Grady, O'Hanraghan,
O'Hartigan, O'Hea, O'Healy (modernized Haley and Hayley), O'Heap,
O'Heffernan, O'Hehir, O'Hickey, O'Hogan, O'Hurly (modernized Harley),
O'Kearney, O'Kennedy, O'Liddy, O'Lonergan, O'Meara, O'Molony, O'Noonan
(or O'Nunan), O'Quinn, O'Shanahan (or O'Shannon), O'Sheehan O'Slattery,
O'Spillane, O'Twomey, etc.
The following were also of the Dalcassian race: the
families of MacCoghlan, chiefs in the King's County; O'Finnelan (or
O'Fenelon), and O'Skully, chiefs in Teffia, or Westmeath.
II. The Eugenians: Of these the
chief families were - MacAuliffe, MacCarthy, MacDonagh, MacElligot,
MacFinneen, MacGillicuddy, O'Callaghan, O'Cullen, O'Donohoe, O'Finnegan,
O'Flannery, O'Fogarty, O'Keeffe, O'Kerwick (anglicised "Berwick" and
Kirby"), O'Lechan (or Lyons), O'Mahony, O'Meehan, O'Moriarty,
O'Sullivan. O'Treacy, etc.
III. The Clan Cian were, as already
stated, located in Ormond or the present county of Tipperary; and the
heads of the Clan were O'Carroll, princes of Ely. The other
families were - MacKeogh (or Kehoe), O'Corcoran, O'Dulounty (anglicised
O'Delahunty), O'Meagher. O'Connor, chiefs of Cianaght (now
Keenaght) in the county Londonderry; and O'Gara and O'Hara, lords of
Lieny and Coolavin in the county Sligo, were also branches of the Clan
Cian of Munster.
IV. The Ithians, who were also called Darinians,
were descended from Ithe, or Ithius, uncle of Milesius.
V. The Clan-na-Deagha were also called Degadians
and Ernans, from two of their distinguished ancestors; they were
celebrated chiefs in Munster, but were originally descended, as already
shown, from the Heremonians of Ulster. Of this Clan the principal
families in Munster were - O'Falvey, hereditary admirals of Desmond;
O'Connell, of Kerry, Limerick, and Clare; O'Donegan, O'Fihilly, O'Flynn,
O'Shee or O'Shea, O'Baisan or O'Basken, and O'Donnell of the county
Clare, etc.
VI. The Irians (or "Clan-na-Rory") of Ulster also
settled several families of note in Munster, as early as the first and
second centuries; of whom were the following: O'Connor, lords or princes
of Kerry; O'Connor, lords of Corcomroe in Clare; and O'Loghlin, lords of
Burren, also in Clare. Of this race were also O'Farrel, lords or
princes of Annaly; MacRannal (anglicised "Reynolds"), lords of Muintir
Eoluis, in the county Leitrim, etc.
VII. Of the Leinster Milesians of the race of
Heremon, were some chiefs and clans of note in Munster, as O'Felan,
princes of Desies in Waterford; and O'Bric, chiefs in Waterford; O'Dwyer
and O'Ryan, chiefs in Tipperary; and O'Gorman, chiefs in Clare.
King Henry the Second, A.D. 1180, granted part of the
kingdom of Thomond to Herbert Fitzherbert; but he having resigned his
claims, it was granted by King John to William and Philip de
Braosa. In the thirteenth century, King Henry the Third gave to
Thomas de Clare, son of the earl of Gloucester, a grant of the whole
kingdom of Thomond or "O'Brien's Country," as it was called; but the
O'Briens and other chiefs in Thomond maintained for centuries fierce
contests with the Anglo-Norman and English settlers, in defence of their
national independence.
