I just found in Census 1891 (free access on familysearch, silly me) , in 1891 she is Maria Brady ,head of the family, married but no trace of James , children cecilia, james L, ellen M and Michael Brady Grandfather (James's of course)born in Ireland, living in Barton, Lancashire.
She seems to be dead in 1901, was she?
I will try to find Marie Emelia (or Emelie or Emilie) Derique ( Derick ,or Derrick , but I bet on Derique )somewhere in France.
I'll let you know.
