Census for 1861 and 1871 - F Lewis

[Ewan]

Hello

I am now looking for the following people on the 1861 and 1871 censuses, can anyone help in searching for them please?

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

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

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

Joseph Dean 49
Sarah Dean 41

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

 Any help much appreciated
Ewan
