Thanks for johns details. Working on what you have posted we seem to be looking for common parents of
1 John born c 1812 place Battersea
2 James born c1819-25 place Lambeth according to census
3 Thomas born c1814 place Lambeth
If they are related.

We know Thomas and James are brothers (1871 census)
In 1871 Thomas is unmarried and we think that James would have married about 1843-4, based on age of first child and relatively young age of wife Eliza (which is fairly consistent throughout censuses). Therefore both brothers would be unmarried in 1841 and possibly living with parents.
A family that could match
address in 1841 Wootten street, Lambeth
Thomas Williams 48 (b abt 1793) Cooper's journeyman
Susannah Williams 48 (b abt 1793)
Thomas Williams 24 (b abt 1817) Comedian?
James Williams 21 (b abt 1820) I think it's bookseller's servant
all born in Surrey

Although Thomas and James's occupations differ, people change to whatever makes them a living
