Sleuths trace fate of first black male slave freed by Lincoln to Minnesota

The grave of a former slave freed by Lincoln
The grave of a man considered the first black male slave freed by Abraham Lincoln is shown at the Rochester State Hospital Cemetery in Rochester, Minn. William Henry Costley was just 10 months old in 1841 when a young Lincoln won a case before the Illinois Supreme Court that freed his mother Nance Legins-Costley from indentured servitude, a status tantamount to slavery. As her son, Costley was essentially a slave, too.
