Thank you Rosie & Spelk for providing the details, as you say Rosie his age is consistent on all the censuses unfortunately I have had no success finding William on the 1851 census
Spelk the detail from the 1911c that would give a marriage date of around
1851 for William Crawford and if I have the correct Louisa Crawford born Calne on 1911 inmate at Camberwell Workhouse, Constance Road, East Dulwich, married 52 years (around
1859)
Register of death Constance Road on 6 Oct 1911
Better late than never?
William Crawford sept qtr 1899 Lambeth vol 1d pg 915 with Louisa Partridge on the same page
A shame the marriage isn't online to view the details
Added - daughter Louisa's 1851 birth entry would that be any help for an address and occupation for William Crawford - an instant digital image is available £3.00 from GRO
