Last night I discovered Miss UK 1851. She was living in Folkstone, Kent in the census of that year, and was living with John Crakford (not sure the surname is correct), Miss Crakford (his daughter) and Miss Jones (a visitor).
She was 15 years old, unmarried, born in Folkstone and employed as a house servant! If you want to check her out she is on HO107/1633 folio 89, page 44.
Seriously though, it is rather sad that her employer didn’t know or didn’t care enough to find out what her surname was.
