Thank you very much for alerting me to this possibility - I hadn't seen it. I have tried but I haven't been able to find the family in the 1841 census yet. This might help rule them out if it was a poor household.

I do have a strong doubt this is the right Elizabeth because the two samplers that are signed in embroidery stitches are clearly by Elizabeth Sisson with no s at the end of Sisson.

Even so I am very grateful for your help.
