Oh brilliant! Thank you, that solves at least one puzzle - but I can't find a marriage for the second Charles Andrews and Kezia ... i.e. this couple in the 1861 census:
6 Wellington Square, St Pancras
Charles Andrews Head aged 30 Cab driver born St Andrews Holborn
Kezia Andrews Wife aged 40 born St Mary Le Strand Middx
and they seem to have all disappeared off the map after 1861!!
