Thanks so much for your help everyone

I can’t work out how to reply to each comment individually so here's all my answers in one place.
Last known record of Hannah:
Admitted to Parish St Martins in the Field 14th Jan 1858.
Descendant through:
In 1851, when Hannah would’ve been 10, her father (and his third wife) had a baby boy Alfred Charles Paviour. I am a descendant of this line. My records show that Hannah was in and out of workhouses by the age of 9, so she may never have met or known of her little brother?
Search for “Paviour”:
Thank you :-) I have tried searching rootschat but can’t seem to find any of the Paviours which I’m looking for like Henry Paviour, Frederick Paviour, Alfred C Paviour, Charles H Paviour, Alfred W Paviour, Clara Paviour, Louisa Paviour …. I couldn’t seem to get any of the other family names listed, to match, (yet!) I’m ever hopeful and will keep searching - thank you!

Thankyou Hillshurst for finding that 1851 census - thats a new find for me.
