I've added it to my own tree as a possible too. I'll keep looking for the family before and after 1841, but so far I can't pin any of them down in the 1851 census. There's quite a few Joseph and Elizabeth Westwoods in the area and Ancestry is full of trees which have combined two or more of these families

... Okay to archive it for now and I'll post again if I find any more links.
