Hi,
This looks like it could be her in the 1901 census but the ages are slightly out from the 1881 and 1891 census.
19 Parker Street, Manchester
Catherine Gelston, H, W, 63, House Keeper, Ireland
Catherine Gelston, Daur, M, 23,. Fuet? Sorter, Wigan
Edward J, Grandson, 7, Manchester
George, Grandson, 2, Manchester
Elizabeth Denis, Boarder, W, 76, Ireland
BTW, I was looking for the death of one of mine once only to discover she had remarried!
Regards,
Mo
