Sherman Peabody was the son of "Old Man" Otis Peabody and his wife Elsie, and the brother of Martha.

He investigated the barn with his father when the DeLorean time machine crashed into it in 1955. Sherman believed the vehicle to be an alien spaceship after reading a science-fiction comic book called Tales from Space. When Marty McFly exited the DeLorean in the radiation suit, the family ran in fear.
