Just one other point, then I'll go away
re 'Enumerator error' - no, not necessarily!
The enumerator simply copied/tried to copy what was written on the original householders census form.
The form was intended to be filled in by the head of the household, in this case a Martha Kennley.
Probably Martha asked Catherine where she was born, Catherine told her, and Martha did the best she could to write down what she
thought Catherine had said.
Then the enumerator, after he'd collected the form, had to copy down what Martha Kennley thought Catherine had said. If Martha's writing wasn't too clear then more errors could creep in.
If you think about it in that way you can see how easy it could be for a slightly unusual place-name to become completely garbled.
