I have a letter dated 1879 to this address. Can anyone find the household in the 1881 or 71 census. I have looked without success, but may have missed it as without a first name there are 100's

Mrs Corlett

22 March 1879

Also trying to find a Miss R A Quine in 1970’s address unknown who corrresponded with my late father, as she was writing about genealogy she may be a board reader
