Here is Matty:
1891 RG12; Piece: 3280; Folio 23; Page 40
126 Margaret Street Ashton under Lyne
William Hall widower 71 yrs Mechanic Iron Turner (retired) b Ashton-u-Lyne
Matty Hyde single 47 yrs General Servant (Domestic) b Dukinfield Cheshire
This fits with the fact that eliza Galt had returned to Ashton in 1891 and the other servant from 1881, Kezia Charlesworth was in service elsewhere in North Meols.
There is a death for her in 1892
It does say 'Mallie' you are right but one can only assume that it is an error
