I am three generations away from slavery with three sets of great grandparents who were slaves.

Monroe and Mary Byrd Markham born 1852 and 1855
Washington and Mary Hardgrave Marshall b. 1822 and 1839 ( This couple had children who were born slaves. My grandfather was the last of their production. Daniel was born in 1886.)
Richmond and Jane Furnace Overton b. 1847 and 1860

My fourth set barely escaped slavery.
William and Alice Mitchell Durr b. 1866 and 1869.
