I don't know how it was indexed, I couldn't find Jane at first either.
I noticed that when Jane married John Harris they were both living on the same street, so I looked for him. The keyword "cab" brought nothing up, but when I used "coachman" he came up straight away. Then I just walked up and down the street a bit and they they were.
Not been able to find Elizabeth Ridge (b 1805) death yet, did she remarry after the 1861 census?
found I think died 1884 aged 80 buried in Burngreave cemetery, lots of people in the grave I wonder if they are all related. I used Elizabeth harris in the search box.
