"The first house at Selma was built by the grandson of 'Madam Mason,' General Armistead Thomson Mason (1787-1819), United States Senator. General Mason was killed by his cousin and neighbor, Colonel John Mason McCarty, in a duel that grew out of political rivalry. Mason had ignored his cousin's challenge and the affair had almost blown over, when, returning by stagecoach from Richmond, he met his old friend, General Andrew Jackson, who advised Mason not to let the challenge pass. McCarty, who had cooled, tried to avert the encounter by making ridiculous suggestions for carrying it out. However, Mason wrote that he 'was extremely anxious to terminate once and forever this quarrel.' To avoid Virginia's recently enacted anti-dueling law, the affair took place near Bladensburg, Maryland, February 6, 1819. Mason was killed and McCarty was dangerously wounded."
