The Freedmen's Bureau (The Bureau of Refugees, Freedmen and Abandoned Lands) was established in the United States in 1865. The Bureau supervised relief and educational activities for Freedmen and Refugees. The records provide modern day Americans with a window into the lives of their ancestors who lived under slavery.
Dr. Maurice Gleeson has initiated research into the Irish input into slavery. Irish names can be found in lists of slave-holders, indentured servants, merchant seamen, sailors and overseers. A search of ancestry.com led to 5 Brennan names (exact spelling only) who were listed as slaveholders in the 1860 Slave Schedules in the United States.

Female age 45, Female age 15, Female age 8
Dominick T. Brennan of Mobile, Alabama

M.J. Brennan of Orleans, Louisiana

There are however many other records which show possible variant spellings of the name Brennan including;
Professor Henry Louis Gates, in his groundbreaking work, has identified the fact that since African men, women and children were identified as property, they are often mentioned by first name in the wills of the slaveholders. A search of the Will and Probate Records of the slaveholders can sometimes identify an earlier generation of an African family or their journey in some instances to Virginia first and then later to other States. Professor Henry Louis Gates, having undergone DNA testing, has established Irish Heritage both on his maternal and his paternal side.
