I see that there is no obvious burial for John in keeping with other family members at Bathwick St Mary:
07.04.1841: Alfred Bright, abode Villa Field, aged 2 yrs 9 months
15.12.1844: Eliza Bright, abode Villa Field, aged 6 months
07.10.1851: Kezia Bright, abode Villa House, aged 55
The family was at Villa Field in 1841, and at Villa House/Villa Field in 1851.
