A ) Oswald is buried outside Dallas in an unmarked grave... Robert Francis Kennedy is to the left of his brother John Fitzgerald Kennedy on the hill of the Lee Mansion
If you go on Google maps and zoom in the are several locations within the cemetery on the map that are noted for specific memorials and burials including the Kennedy's
JFK is located near Robert E. Lee's home on the hill. If you need directions, just ask a security guard or go inside the buildings as soon as you enter the cemetery:)
