Thank you
so much, slowly but surely a little more info is coming to light

I am almost 100% certain that this is the person I am trying to trace.
Catherine Kelly at 16 Salisbury rd shown as widow .DoB 9 Sept 1877 Domestic duties.
After consideration, she was probably retired by the age of 62 and no longer teaching. I am certain she taught from 1932 when she arrived in Dover, but still need to find evidence of it. Do you perhaps know what the retirement age was in the '30's? And would domestic duties just mean 'stay at home'? Am wondering why she wouldn't have put 'Retired'. Perhaps just a foible of the way Census is done or was done...
