Yes, Thomas and Jane and their family must have moved from Wraysbury to Chiswick some time between the births of Elizabeth Jane and William. They also had another son - Robert - born around 1834. Some time between 1833 and 1837 Thomas died and Jane remarried. I have not been able to find a marriage for her but this is the family in the 1841 census in Chiswick:
Ref: HO107/689/1 Folio 31 Chiswick
John CRESSWELL, 40, Ag lab, Not born in the county
Jane CRESSWELL, 40, Not born in the county
William ROW, 13, Born in the county
Robert ROW, 8, Born in the county
Sarah CRESSWELL, 2, Born in the county
In 1851 the families are still in Chiswick, living not far from each other:
Ref: HO107/1699 Folio 404 Schedule 76 - Gunnersbury Place, Chiswick
Joseph WICKS, Head, Mar, 31, Labourer, born Middx Harefield
Jemima WICKS, Wife, Mar, 27, born Bucks, Wraysbury
Elizth Jane WICKS, Dau, Unm, 6, born Middx Chiswick
Eliza Ann WICKS, Dau, Unm, 4, born Middx Chiswick
Daniel WICKS, Son, Unm, 2, born Middx Chiswick
Jno Jas ROWE, Nephew, Unm, 2, born Middx Chiswick
Ref: HO107/1699 Folio 431 Schedule 155 - 2 Square, Turnham Green, Chiswick
William ROW, Head, Mar, 23, Ag lab, born Middx Chiswick
Rebecca ROW, Wife, Mar, 22, born Middx Chiswick

John CRESSWELL, Head, Mar, 40, Ag lab, born Surrey Lambeth
Jane CRESSWELL, Wife, Mar, 42, born Bucks Wraysbury
Robert ROWE, Son, Unm, 17, Fishmonger, born Middx Chiswick
In 1861 Jane is still in Chiswick:
Ref: RG9/780 Folio 55 Schedule 130 - 7 Pack.....?, Chiswick
John CRESSWELL, Head, Mar, 58, Labourer, born Surrey Lambeth
Jane CRESSWELL, Wife, Mar, 62, born Buckinghamshire
John ROW, Grandson, Unm, 12, born Chiswick
I think the above John ROW living with John and Jane in 1861 is the same child who was living with Joseph and Jemima WICKS in 1851.
