Mary was frightened, as her brother, Jefferson Stephens was on duty as a guard at Johnson’s Island. She slipped out of the rooming house, and hurried to the home of her sister-in-law, Mrs. Washington Stephens. Washington Stephens, Mary’s brother, was stationed in Washington D.C. at the time. The proper authorities were tipped off, and, perhaps sensing this, the plotters aborted their plans -- but not before they hijacked two steamers, the Philo Parsons and the Island Queen (both shown below).
In 1867 Mary Marilla Stephens married Jesse Greene, who was a descendant of the Taylor and House families who settled in Perkins Township in 1815. They had five children. Mary was widowed in 1894, but she lived to the age of 93 years. Her obituary stated that she was “one of the best known women in Erie County.” She had been a member of the Perkins Methodist Church, Ladies Aid Society, Home Missionary Society, and was a charter member of the Perkins Grange. She is buried in Perkins Cemetery in the Greene family plot.
