Your general question "Is there any way to tell where she or her family originated? " had been specifically answered by yourself in an earlier thread - the lady in question's birthplace is shown in censuses as Leverington c1823. Perhaps your question should have been "Can anyone find her baptism in Leverington so I can get her parents' names"
But moving on from semantics, there are no Madmores anywhere that I can trace, and I've struggled to find her marriage to Edward Rutter. I finally found it on
www.freebmd.org.uk where it's recorded as Edward Rutty and Elizabeth Wadmore in Wisbech registration district vol 14 page 263 in the Dec quarter 1842. The local register office -
http://www2.cambridgeshire.gov.uk/db/ridmars.nsf/search?OpenForm - shows it as Edward Rutty and Elizabeth Meadmore
In 1841 in Leverington there's Edward Wadmore 45 ag lab, Elizabeth Wadmore 45, Sarah Wadmore 9, Ann Wadmore 6. Edward & Eliz not born in Cambs, the two younger ones born in Cambs.
In 1851 still in Leverington were Edward Wadmore 57 born Hilgay Norfolk, and Elizabeth Wadmore 57 born Stanground Huntingdonshire. I can't see their marriage.
If you check
http://www.cfhs.org.uk/BaptismIndex/index.html you'll find Elizabeth baptised in 1822 at Leverington, daughter of the above Edward and Elizabeth, along with her siblings - just put Wadmore in the appropriate box on the search page.
