Mary Ann CULL Wife 27 Cheltenham, Gloucs
Frederick Witton CULL Son 2 Erdington, Warwicks
Alfred Ernest CULL Son 2 mo Birmingham
Cornelius is lodging in Birmingham (unmarried) in 1851.
He is in Bengeworth in 1841, probably with his parents and siblings, but the census image is practically illegible...

However, the LDS Pilot Search site
http://search.labs.familysearch.org has a likely baptism for him:
Cornelius CULL, son of John CULL and Rebecca, baptised at Bengeworth on 1 Oct 1826.
Other children baptised at Bengeworth by John and Rebecca:
Drusilla - 7 Nov 1826
Pheophilus - 7 Nov 1826
Priscilla - 7 Nov 1826
Bazall - 7 Jun 1829
Cleophas - 26 Jan 1832
Usilla - 22 Mar 1835
So based on that, this looks like the family in 1851:
HO107/2044/76/31 - Church St, Bengeworth, WorcsJohn CULL Head 66 Labourer Evesham, Worcs
Rebecca CULL Wife 57 Southampton
