My GGGrandmother was Eliza BRUCE (1843). She married John Winterbottom SMITH (1843) in 1863 in Manchester, where John said his father was William Winterbottom SMITH - Cabinet Maker.
On the 1871 the family are using the name SMITH (though I've only found Eliza and the children), but in later censuses they are using WINTERBOTTOM and use this name throughout.
I cannot find "William Winterbottom SMITH" and the only place I've seen the name John Winterbottom SMITH is on the IGI but that gives his father as "George Winterbottom SMITH" and mother as "Martha"
Today I have finally found what I believe to be the family on the 1861 Census in Hulme -
RG9/2891/106/17
William (1808) bn Nottingham, Nottinghamshire, Joiner
Martha (1818) bn London, Surrey
John (1843) bn Manchester, Lancashire
Isabella (1853) bn Manchester
I cannot find them on any of the other Censuses

Can anyone else find them or suggest anything that might help please?
Thank you
