Irish Surnames and Slave ownership

McLysaght's "Irish Families" cross referenced with the U.S. Slave Schedules (1850) and the Slave Compensation Records (1834). I believe that my data, while cursory, is suggestive of the level of slave-ownership among those of Irish descent. Hopefully this ‘first pass’ review will lead to more in-depth research that will tease out the complexities of these family histories.
