Don't go near the record office then - seems the cathedral grounds have been reordered a number of times (including the late 1800s and the 1930s) - record office has copies of letters of complaint when, in a previous reordering, headstones were buried underground at the cathedral!! Don't know if my John's parents, Henry and Elizabeth (nee Fielding) Butler, had a headstone (they were buried at the cathedral) but have never found it!! :-(
