More on The Families
MacCarthy rules Cork and Desmond
The MacCarthys were the most powerful family of Cork
from the time of the Norman invasions onwards.
They are given in the 12th century by O’Heerin thusly;

“Heroes of Munster, from the fortress on the Shannon,
Are the race of Eogan, the son of Olild, MacCarthaigh,
the maintainer of its tributes,
Is like an incessant stormy wave”

The MacCarthys as the most powerful Munster
family, held continuous battle with those who
came to settle and conquer the area. They
even retained the title of ‘Princes of Desmond’
down to the reign of Elizabeth.

Many branches of MacCarthy Tree
There are many branches of the family
found in history, and they are sometimes
found on both sides of a given battle.
Two great branches of the MacCarthys are
often given as; the line of the Mac Carthy Mor,
of whom Donal McCarthy was created earl of
Glencare in 1565 A.D. by Queen Elizabeth; and
the line of MacCarthy Reagh, princes of Carberry.
The MacCarthys held many titles and Castles
over time in Cork and Kerry. (see also ‘Families
of Co. Kerry ).

Inauguration of the chief
O Rourke, Mac Egan, O Daly, O Duinin,
O Sullivan Mor, O Donoghue Mor

The Clans come together
Windele finds that the MacCarthy Mor was inaugurated
at Lisban-nacuhir in Co. Kerry, at a ceremony presided
over by the O’Sullivan Mor and the O’Donoghue Mor,
fellow Eugenian chieftains. His captains of war are
given at that time as the O’Rourkes, presumably from
Breffny. The MacEgans are found as his hereditary
Brehons and the O’Dalys and O’Duinins are given as his
hereditary poets and antiquaries.

Families Before the 12th Century
In preparing a list of Irish families in Cork prior to the
12th century Norman invasions of Ireland we will rely
on listings from Keatings History of Ireland, and from
the “Chaoilli” manuscript. (The latter will focus only on
a very specific portion of Cork – known as O’Keefes Country).
By the time of the violent upheavals of the 17th century,
many new names had been settled in Cork. Some
members old Irish families had adopted English ‘surnames’
of their own as well.

More Resources
The ‘census’ of 1659 will give the researcher some
details of the change of land ownership in that century.
We have listed the chief family seats of power in 1741,
and the reader will readily note the lack of old Irish
names in that account. (Enumerated on following pages.)
A listing of names from the 1659 census, barony by
barony is included in the book)

Irish Family Origins, part one

Todays notes:
From “The Families of County Cork, Ireland”
including leading families of Munster. part 1.
More information found here:

More Anciently
“The families of Cork have had a tremendous
effect on the whole of the province of Munster.
Ancient Munster was comprised of North
Munster presently called Thomand (see
Families of Co. Clare); South Munster today
recognized as Desmond (Cork); East Munster
(Ormond); and West Munster.

O’Brien and MacCarthy Rise
In The Families of Co. Clare we saw the
rise of the Dalcassions in Clare under Brian
Boru. The O’Briens of Clare, (North Munster),
would break from the control of The MacCarthy
and the Eugenian families of south Munster.
In the 12th century MacCarthy no longer held
sway in the north of Munster.

Families of Co. Kerry
At about the same time, in The Families of
Co. Kerry, we saw the family of O’Donoghue
move into Kerry from Co. Cork and establish
itself as pre-eminent in the beautiful area
around Killarney. The O’Donoghues were
another Eugenian family of Munster, who
replaced the existing ‘Eoganacht Loch Lein’
in Kerry, which included Moriarty, Cahill,
Flynn and O’Carroll. Some even theorize the
Eugenians as originating in that part of Kerry.

Mahoney, Kirby, Sullivan, O’Keefe, Callaghan….
There are many branches of the Eoganacht
families found in this book. Eoganacht
Raithlind anciently held south Cork, represented
by O’Donoghue and O’Mahoney. Eoganacht
Glendamnach ruled over Fermoy under O’Keefe.
Eoganacht Aine is found under O’Kirby.
Eoganacht Caisil (Cashel) claimed supremacy
over all most anciently, and of this line are
most often given Sullivan, MacCarthy and
