I may be wrong but I think Speen is in Berkshire(sorry you posted under Berkshire).
Did she marry in 1856 John Keeves Pountney and in 1861 in she living as a mother in law with her daughter Charlotte Miller and son in law James E Taylor and family in Claines in Worcestershire?

If so could his be her in 1871living at Edgebaston Birmingham and listed as born in Salisbury?

Yes, that would be her. I posted under Berks as I wondered if the parish had been part of Wiltshire sometime earlier, as places further east had been. With regard to the findmypast transcription, on the previous page of the census is the word "carpenter" (for Peter Pledger), where the "p" closely resembles the second letter of her birthplace. We're getting down to aspects of regional accents and transcription here, but I thought perhaps "Spine" = "Speen". It is possible that the word is "Spere"; there is one reference online [
http://history.wiltshire.gov.uk/community/getfaq.php?id=529 ] that might imply a placename but extremely localised. Interestingly, it's near Salisbury. But wouldn't the census entry refer to a parish, village or township?
KGarrad: Yes, I could have wished for better handwriting.
Another point: at least two of her children were listed as born in Highworth, GLS. However, there's a Highworth in Wiltshire, as opposed to what now appears to be a tiny part of Cheltenham. I should add: her "common law" husband from 1822 to his death in 1846 was a wealthy man - William Miller of Ozleworth Park in Gloucestershire. These various places of birth (or at least baptism) for children imply a fairly mobile life.
If there was a Speen baptism to more or less match I would feel less insecure about my assumptions.
