Boothville is a town named for Milo Booth, a famous silent film actor who was also buried there.
The Scooby-Doo Show
The Ghost of Milo Booth side-tracked the gang to this town so they could see a tomb he had re-labeled as Milo's was empty, and hopefully be convinced the ghost was real. He was not expecting the exposure of his Scooby-Dee impostor. When that happened, he tried to trap them in the tomb. (The Chiller Diller Movie Thriller)
