1861 and 1871 Census

[Ewan]

Hello

This is just a shot in the dark so if anyone is able to track these people down it would be greatly appreciated.

Frederick Lewis b 1817 Compton Bishop  Somerset
Harriet Lewis b 1815 Chippenham  Wiltshire

On the 1841 census they were living in Compton Bishop Somerset
In 1851 they were living in Weston Super Mare

It doesn't look like they are able to be found in Somerset, and as Harriet has her roots in Wiltshire, I wondered if perhaps they were there when the 2 censuses were taken.

I have found a Harriet Lewis on the 1881 living at Wedmore  Somerset stated as a widowed mother in law.

I wonder if this is the Harriet from Frederick and Harriet that I am searching for on the 1861 and 1871 censuses?

Thank you
Ewan
