A couple of points from your posting.

1/ I could not find Sarah Robbins in the 1851 or 1861 Census hence the possible death in 1846. This is the burial:

Name: Sarah Robbins
Gender: Female
Birth Date: 1785
Burial Date: 29 Nov 1846
Burial Place: Bristol, St George, Gloucestershire, England
Burial Age: 61

2/ There is a Staunton near the border of Gloucestershire and Worcestershire and a Staunton in the Forest of Dean between Coleford and Monmouth. The marriage of Noah Cutter to Anne Gough took place in the latter.
