Martin Hemings
In 1792, Thomas Jefferson wrote that he and Martin Hemings had had a disagreement or fight.  He did not say what the fight was.  He told one of his managers at Monticello that he and Martin Hemings had agreed on what to do: Jefferson would sell Martin Hemings to someone else.  Martin Hemings was 36 or 37 at the time.  Jefferson told the manager that Martin Hemings could choose another master.  He said he did not care how much money he got for Hemings, so long as Hemings was gone.  He also told the manager that he did not want to free Martin Hemings, the way he would free his half-brothers Robert and James later in their lives.
