Brennan Genealogy & History

Brennan is an old Irish descriptive name, dating back to the O'Braonain clan. The derivation is Old Gaelic, either "braon", meaning teardrop, or "bran", meaning raven, which would describe someone with black hair. The ending is the diminutive suffix "an". Brennan genealogy includes the variations Branon, Brennyn, and MacBrennan, among many others. Brennan family history includes a family seat (feudal manor) in Kilkenny in ancient times and a legend that several of the O'Braonain clan became "highwaymen" (thieves). Today Brennans are found in Mayo, Sligo, and Roscommon, where they were chiefs in 1159-1488. The first emigrant to America arrived in 1731 in Potomac.
