Still in lateral thinking....
This is likely to be the 1881 Christopher SCHEIFLER's widow:
1894: Kelly's Directory Pork Butchers, Northumberland
Mrs Amelia SHENFLER, 125 Church Street, Walker, R.S.O.
George SCHENFLER, 71 City Road, Newcastle
CENSUS 1891:
RG12 - Piece 4231 /Folio 90 /Pg 62
127 & 125 Church Street, Walker, Longbenton
Head: Amelia SCHEUFLER 45, widow, Pork Butcher, b Germany
Son: George SCHEUFLER 21, unm, Butcher, b Germany
And their son:
MARRIAGE: Jun Qtr 1893
George SCHEUFLER
Katherine TRUCKENMUELLER
1901: 32 Glue House Lane, Elswick, Northumberland
RG13 Piece 4770 \Folio 168\ Pg 40
Head: George SHYFLER 31, Pork Butcher, b Germany, German Subject
Wife: Katerine SHYFLER 31, b Germany
Son: Frederick SHYFLER 2 mths, b Newcastle on Tyne
CENSUS 1911: Need to look up Amelia (we can't do 1911 look ups here on RC). Can't find her in 1901, either - but I think this is her death:
DEATH 1918:
Amelia E SCHEUFLER age 72, Re: South Shields Co Durham
And possibly the marriage of a daughter (this Rosina is likel to be the same Rosina SCHENFLER a Servant working in Northumberland in 1891, age 18).
MARRIAGE: Mar Qtr 1897
Rossine SCHEUFLER
