Catherine Cookson's The Dwelling Place

A bare stone shelter is all that protects Cissie Brodie and her brothers and sisters from the workhouse after their parents die in a cholera epidemic.

On hearing of the family resemblance the Lord decides he must have the child. Lord Fischel wishes to buy his grandson off Cissie but she refuses until Bella is caught steeling.

Isabella is not happy and tries to kill Cissie but Clive kills her first and Matthew helps him to make it look like an accident.
