Thomas Bell (ahnentafel [22])

[kiterunner]

This is that family in 1851, at Newby, Cummersdale:

Jane Bell Head Widow 64 Farmer of 60 Acres 1 Labourer Cumbd St Marys
Jane Bell Daur U 34 Do Do
Robert Bell Son U 32 Do Do
Elizabeth Bell Daur U 18 Do Do
Wm Armstrong Servant U 50 Farm Servant Do ????
Robert Dalzell GrandSon 9 Do St Mary's

Presumably Robert Dalzell belongs to the next household:
Hugh Dalzell Head Mar 53 Handloom Weaver Ireland
Isabella Dalzell Wife Mar 40 Wife Cumbd St Marys
John Dalzell Son 7 At Home Do Do
William Dalzell Son 5 At Home Do Do
Jane Dalzell Daur 4 At Home Do Do

I'm thinking that if we can find baptisms for these people it should give us a better idea of which parish your John and Mary Bell would have been baptised at, and hopefully we will find they are related to these Bells too.
