Aha, two Charles Kewley's, both barbers, both living on Factory Lane in the 1841 census. No wonder we get confused.
I don't have the detail reference, but from some notes compiled 20-odd years ago:
Factory Lane 1841 census

Charles Kewley 66 [? faint] Barber Y

Judith Kewley 66 [? faint] Y
The ages match well to their baptisms 1773 and 1774. These are my 3g-grandparents.

I can't help but think there might be a connection between these two Charles Kewleys, with same occupation on same street at same time. Hmmm. This might help with something (maybe?).
