Dear Marg,
I had a quick look through for you and found a few deaths on Brian's site for burials.
KELLY, Robert 48 Lon 27 Jul 1870
KELLY, Elizabeth Margaret 45 Lon 7 Jul 1867
KELLY, John Robert 18 Lon 25 Mar 1868
KELLY, William Henry 15 Lon 23 May 1867
KELLY, Richard Charles 83 Dbc 30 Mar 1939
KELLY, Thomas Edward 12 Lon 24 May 1865
Not sure if they are yours but dates and second names fit, especially for most of them not showing in other census (except for Richard Charles).
Why don't you ask for some MI's and see if that helps.
Regards Diane
