Need help please trying to find  Sophia Faulkner and her sister Mary A on the 1901 census.  Sophia was born 1877 West Bromwich and Mary A was born 1885 Chirk Denbigshire. 
1901 their mother now a widow and brother John are living at Inkerman Street Oldbury , and in 1891 the family were all together at Chirk Denbigshire.
I can’t find Sophia or Mary at all and would very much appreciate any help trying to find them both.
Thank you 
Annie
