Hi Jaime
I see that by 1911 she is using Emily, not Eliza so on that basis I think that this could be them in 1891:
21 Station Street , Middlesbrough
Edward Sharp 55 Labourer At Gas Works Cranbrook, Kent
Elizabeth Sharp 46 London
William Sharp 11 Son Linthorpe, Yorkshire
Emily Sharp 8 Daur Linthorpe, Yorkshire
John G Sharp 7 Son Linthorpe, Yorkshire
Elizabeth Peckman 23 Daur London
Frederick Peckman 2 Grand Son Middlesbrough, Yorkshire
Jane E Peckman 1M Grand Daur Middlesbrough, Yorkshire
Linthorpe is a village within Middlesbrough.
NOTE: Not sure that "Peckman" is the correct transcription, it could be something starting with an "R" - difficult to read
