Great-Great-Grandpa Marsh

Great-Great-Grandpa Marsh was Marvin Marsh 's grandfather (making him Stan 's great-great-grandfather).

Apperance
He was a very old caucasian male, and seemed somewhat thinner and taller than his other descendants.

The name confusion Marvin has appears to be genetic, as the ghost of Stan's great-great-grandfather called his grandson "Billy" instead of "Marvin" in the episode " Death ".

Episodes

 * "Death " - Seen as a ghost.


 * "Hummels & Heroin " - Seen dressed in a picture on Marvin's room in Shady Acres.
