Thanks again MP.

I printed off the 1881 census with Alfred Evans last night. It transpires that the address is <5 minutes walk from where Sarah Anne Davi(e)s lived on the 1881 census, so it has all fallen into place.

Now to get the GWR records. They didn't prove that difficult for Henry my Gt. Grandfather, so hopefully I'll have success again.

Cheers for all the help.
