On the 1851 census there are no Sallys born within 5 years of a birth circa 1812 in Denham Suffolk (I believe there are two Denhams in Suffolk). There are 4 Sarahs.

The 1861 census has 6 Sarahs. Besides the 4 already mentioned are
Ousden Suffolk
Sarah Day 47 Denham, Suffolk, Wife
Sarah's husband was James Day 46 a farmer and miller born Bradley Suffolk. James probably had a different wife on the 1851 census in which case I'm not sure where and who this Sarah was in 1851.

Sarah's husband was James Ashman 55 an ag lab born Denham.
(Sarah was 35 in 1851 and born Dalham)
