In 1868, John Brannon of Nenagh Tipperary opened an account in the Freedman's Bank in Tallahassee, Florida. He named his brother Thomas of Nenagh, Tipperary, Ireland on his account.
Unfortunately he did not give any other information.
I'm a Brennan with clear roots in Clawinch Island, Co. Longford (on the Shannon) Brennan Family Clawinch, Co. Longford and possibly in Kilteevan, Co. Roscommon. As a child my father's people told me that our family came from Kilkenny originally and that Cromwell threw us out. This story has intrigued me all my life and of late I have begun to collect information about Brennans the world over. If you have Brennans in your family, you are cordially invited to join me and maybe we will get to the root of this family story, or maybe not...
