"Do we have those Stanleys in 1851?

Coincidentally, living in the same house in 1861 are two Harriets. Surname Robinson.
One Harriet is forty something, and the other, her daughter, is eleven. Both born St Geo East.
Head is Willm Robinson, 32, Chair Maker.
Not sure if they are about in 1851 either? "
This is who I have been thinking was my Harriet aged 11 with her mother Harriet aged 40 Living under the name of Robinson

As far as I know no one has found that family in 1851, I do not have subs to Ancestry or FindMyPast so I cannot look.
