I have a great-great uncle in a wax museum in Texas.
edit - Oh, wait, it's not him in the museum, it's the four men who killed him, and they're hanging by their necks. His name is just on the description of the scene. And he wasn't technically an uncle, more like the uncle of my maternal grandmother's cousins or something like that.
There's also a former governor of Mississippi, who has a lake or reservoir named after him, distantly related on my father's side.
