Anyone recognise this book?

[hugoagogo]

Set in 19th century maybe early 20th.
Poor widow living in a grotty room with 2 dc; she scrapes a living working in a laundry or something.
Then she dies and oldest dd takes over her job.
They save money in a leather bag up the chimney.

Yes, but can't remember what it was called! Isn't the mother from a wealthy family and was cut off for marrying beneath her?

Oh oh was it The Forgotten Garden by Kate Morton??

Does she eventually go back to the house to try and rescue a brooch? Big house and cliffs in it somewhere too?

I think I've read it and it will come too me... eventually

Possibly-I can't remember how she ended up in such straightened circumstances.

Also something about holes in the walls + the children peeking out of them?

Thanks for trying.

If its the one I'm thinking of I think Poledra has it.

Is it the Forgotten Garden by Kate Morton? She goes to live in Cornwall with her relatives?

Is it Slammerkin?
