Part I. Topography of Thomond Chapter 3. Burren, or Corcomroe
Families of O’Loghlen and
O’Connor; Islands of Arran formed part of Corcomroe; Historical
notices of Corcomroe
The name and the area of this territory are preserved
in the modern barony. Its name in Irish is Boireann, which signifies the
rocky district, being compounded of Borr, great, and onn,
a stone or rock. Its chief inhabitants were called after the introduction
of the use of surnames O’Loghlen, from Lochluinn, the chief of the
territory A.D. 950 in the reign of Callaghan Cashel. The name Lochluinn
does not appear in Irish history till the ninth century, and there is
every reason to believe that the Irish borrowed it as well as Manus, Randal,
Amlaff, and many other names from the Danes, who had formed intermarriages
with many of the native families. Previously to the tenth century Burren
had the name of Corcomroe Ninnis, from the tribe who inhabited it, called
Modruadh Ninnis. This people split into two families, and divided their
lands into two nearly equal parts, which they styled East and West Corcomroe,
the former being ruled by O’Loghlen, and the latter by his rival
and kinsman O’Connor. There are, however, instances of O’Connor
having become chief of both the divisions long after the formation of
them and after the establishment of surnames, and vice versa
of O’Loghlin having extended his sway over O’Connor and West
Corcomroe. In the fourteenth century, however, they became two chiefs
wholly separated and independent of each other. 
Their relationship is set forth in the Genealogical Table, which is given
at the end of this chapter. It may be remarked that for several centuries
the three islands of Arran belonged to Corcomroe.
