Jasper Jones was a human man.
The brother of chambermaid Anna Jones, Jasper was a devoted manservant in Ravenswood Manor, and prided himself in "keeping the Master happy" (though certain gossips liked to joke that his sister "kept the master happier", which, knowing Henry's womanizing ways, isn't too hard to believe). Having died alongside his sister in the 1860 earthquake that swallowed up Phantom Canyon, he was buried near her, just outside the Manor, in Boot Hill Cemetery.
Behind the scenes
Jasper Jones's tombstone is seen in the ride Phantom Manor, opened in 1992.
It is unclear if he and Anna were related to Milo Jones, the outlaw from Thunder Mesa.
