Hi. I have found Mary on the 1911 England Census. Surname spelt DUSCOLL

The names have been wrongly transcribed - Mary Duscoll - Mary is 25 an umbrella maker and living
with her widowed Mother Alice and brother William.

Alice is age 72 and says she has been married for 41 years - she had 8 children and 6 are
still living.

There are 2 births - Catherine M Quinn Mothers Maiden Name Driscoll and Mary W Quinn
Mothers Maiden Name Driscoll - Both born Jan Feb March Quarter 1916 Manchester - they must have been twins.
Hope this helps a bit
Norma
