Sarah Moore Head of Household in Islington in 1861 born circa 1827 Warminster has 4 children with her all born Islington, starting with John Edward aged 14, Mary Jane 12, Thomas William 9 and Joseph Henry 2 - the child Henry on the 1871 census.
1851 census and the family is in Islington with husband Joseph aged 26 a railway labourer. The 1861 census does have a Joseph born Warminster a stoker in the Royal Navy, so if that is him he was only a relatively short time in the navy.
Ann Morris, Joseph's sister gives Warminster as her birthplace on the 1851 census (but then so do at least 20 other Moores). Joseph is not with his sister on the 1841 census.
There is this baptism in Warminster
MOORE, Joseph
Christening Date:5 Jan 1825 St Lawrence Warminster, Wiltshire
Father: Thomas MOORE
Mother: Sarah
as well as one in 1831 to parents Richard and Elizabeth. No baptism for an Ann.
The baptisms just tend to indicate there are other potential Joseph Moores born in Warminster.
I can't find any Chadwicks either in Warminster in 1841 or born Warminster in 1851. I can find a Sarah Langley of about the right age though in 1841 in Warminster.
