Thanks again Olliecat, I found Lettie Pearson in 1901 working as a cook/domestic for a Nottingham solicitor, ten years earlier she was living in Stapleford with her parents, Jonas and Martha. It appears she was born in Newbold Moor, Derbyshire. It does look like may have returned fetch Letty after her son was born.
Will definitely try to access the 1911 census as soon as possible. Thanks again for all the help. If I can ever be of assistance please do contact me.
