For the year 1088  (A battle is described which mentions Bruree and Drumain-ui-Cleirchen.  In essence, the Ui-Fidghenti were driven out of  Limerick  as a result of this battle.  The Cleirchen who remained in Limerick became Clerys and Clarkes.  Other Cleirchen went to Tipperary where they established Ballycleireachain[Ballyclerihan], which they held until the coming of the Normans about a hundred years later.  Interestingly, the family who took their lands in Tipperary were named MauClerc,  a French name meaning "Cleric," which was anglicised to Mockler.  Remains of the Clerihans' settlement still exist outside the modern village of Ballyclarahn.

Other mention of the ancient O'Clerkins:

The History of Ireland by The Rev. Geoffrey Keating:      Cleirkin, King of the Ui Barchi is mentioned in an account of the Battle of Belach Mughna in 903

Keating cites O'Heerin's verse:

The Rock of Cashel

"The portion of the delightful Dal Carbri Eva,
Princes of Cashel of white standards,
Lasting is his prosperity to the country,
The brave and high chief O Cleircinn."

This was probably written about Cairbre MacCleirchen, Lord of Ui Fidhgeinte, who died in 1013.  The kings of the Ui Fidhgeinte and other kingdoms in Munster gathered at the Rock of Cashel, as did the kings of the north at Tara.  Cashel is where the Kings of Munster were crowned.)
