Thanks for the suggestion but Elizabeth Dickens died in 1863. Like you, my first thought was a Dickens character but I can't find a death in 1849 to tie any of them up too ... sigh
Frustratingly, one inspiration for a character in Dickens died, in reality, in 1849. Hortense, the murderous maid who kills Tulkinghorne in Bleak House, was based on the murderess Mrs Manning , hanged in that year. Dickens attended the execution. But she obviously didn't die IN York Buildings, even if she ever had any connection with them, so the trail, as they say, goes cold. Still, if it is a Dickens character, that only leaves 988 named characters to go !
I get what you're saying Smouse but "If you Google it" is any answer to any question.
Maybe a clue in which direction to Google would have helped? I hope you see my point. No slant was intended.
Charles Dickens, then 12 years old, was boarded with Elizabeth Roylance, a family friend, in Camden Town.[18] Roylance was "a reduced [impoverished] old lady, long known to our family", whom Dickens later immortalised, "with a few alterations and embellishments", as "Mrs. Pipchin", in Dombey and Son.
