Thanks everyone.
Does anyone have access to (or can point me to a web resource) for a trade directory for Darwen in 1841 that might show what the shop was?
My next step is to work out if her husband Henry was dead by 1841, or just somewhere else.
I suspect he must have died - wives in the Wild family seem not to worked outside the home. The men were almost all plasterers, painters and decorators: the painting & decorating trade went right down in the family into the 20th century (and for all I know there may still be some Wilds in the Darwen area painting and decorating)
