I'm posting the full census details as it makes it easier to follow than having to turn up the entries each time
1851
John Ficken 28 b Stepney
Betsy 23 b Ongar
George 5 days b Whitechapel
1861 - the enumerator has made a right mess of the entry. Only one birthplace shown despite 4 entries for children. There appears to be 2 Franks - one aged 9 and one aged 4
John Ficken 37 b St Clements
Betsy 32 b Ongar
Edward 7 (Edward George b 1854)
James 11 (not on 1851 census)
Frank 9
William Wood ??

John Ficken 50 b Stepney
