This is believed by many to be Jesse Garon's unmarked grave at Priceville Memorial Gardens in Tupelo, MS. He has a memorial marker at Graceland with his name misspelled on it.
Stillborn twin of music legend Elvis Presley. He was the older of the two. Elvis would visit his grave frequently as a child and never quite got over the fact he had been chosen to live while his twin brother had died.
