Was wondering, given there is no sign of John with a father Robert, a plater, showing in 1881/1891 Scotland, whether the family had moved to England after John's birth, and I think they did. From 1881 (again, a little bit further luck that it doesn't just say Scotland for John's birth or his family's birth places

):
Robert Bell 32, Plater (Ship) - can't make out Robert's birth place as yet, showing as Heirshire, Scotland
Margaret Bell 28 b. Belfast, Ireland
John Bell 9 b. Patrick, Scotland
Minnie Bell 8 b. Patrick, Scotland
Robert Bell 4 b. Patrick, Scotland
Esther Bell 2 b. West Hartlepool
Address: 21 Dover Street, Hartlepool
From this entry, I think parents are Robert Bell and Margaret BENSON. Two birth entries show for children, one of them John on IGI:
John Bell b. 14 May 1872 Govan, Lanarkshire
Samina (Minnie?) Bell b. 26 August 1873 Govan, Lanarkshire
Can't easily see parents' marriage so far, but John's birth cert above from
www.scotlandspeople.gov.uk would let you confirm family details further. Births cert in Scotland include date and place of parents' marriage (from early 1860s) to help you work back. The cert should also have the right occupation etc. for father Robert.
