The 1897 burial at Beckett Street - 7 March 1897 - James, son of John Bell, 45 Argyle Place - aged 9.
Grave number 11725, which, I'm assuming, is a children's grave from the ages shown.
Not that this helps with burial of your John Henry Bell and you probably already have this information
For info....daughter Florence’s baptism on 18 May
1898 has address
35 Argyle PlaceWas his wife named Laura? If so, it looks as if she died
1936 and is buried at
Harehills Cemetery, Plot

address
5 Azalea Streetthese four people appear to be living at that address
Laura 1869 b Portsmouth
Blanche 1891 b Cardiff
Foster 1898 b Leeds
Catherine 1902 b Leeds
I wonder if Foster has been mis-transcribed and should actually be Florence

Was that the same address on John's 1921 death certificate?
