Hi
It is a difficult one. There were a few Ann Turtons about in the north of England of a similar age, so it certainly isn't certain that it was your Ann Tarleton who had that sad accident.
On the face of it she seems a slightly unlikely candidate, though on the other hand she has disappeared after the 1851 census.
I was minded to think maybe it wasn't her, but there is something...
Sorry to harp on about Elizabeth, but do you know what happened to her? I noticed from the free index on findmypast that there are some possible admissions for her to Liverpool workhouse. Of course it may not be her, but she would be a candidate.
They are also on FamilySearch

The thing is, the Lock wards in workhouses were for women with sexual diseases (sometimes there were wards for men as well)
So rather like the lock hospitals. Often associated with prostitutes
