Seward, Secretary of the State in the plot to kill Mr. Lincoln. Seward's son was nearly beaten to death by Lewis, and William Seward was stabbed several times in the face, both survived. Powell was originally buried at the execution site, but during the next twenty years his remains were moved and reburied several times.
