Brennan

 

About the study

This study has emerged from a desire to find the truth, if any, in a story I was told in the 1960's. A family member told me that though our family can trace it's roots to Clawinch Island, County Longford, Ireland, long ago Cromwell kicked the Brennans out of Kilkenny, sending one branch of the family to Kerry and the other to Roscommon/Longford.

Braonain from 'braon' meaning tear, sometimes translated from the Irish language as meaning 'of the tears' or 'of the sorrows' It could be said that in fact 'Brennan' is the variant since O Braonain is the older Gaelic name.
