There's an Ethel 'Vanneby' on the 1901 Census.
1 Thames Street West, Wallsend listed as a servant to John Wilson. She's aged 16 and says was born in Newcastle, but if she had been living there all her life and the head filled out the form, then it could be her.
If you can look at the page on ancestry, it could be Vanneley with the l & e running into each other to look like a 'b'.
The source citation is Class: RG13; Piece: 4795; Folio: 24; Page: 39
