First appearance: Mrs. Montacute Jones's Garden-Party
As a major figure in The Duke’s Children, Isabel Boncassen is not background color—the story leans on what they do once the chapter opens.
The American beauty who charms Silverbridge with her vitality and wit; they walk and talk together.
Isabel Boncassen arrives in England with her scholarly father, charming everyone from the Duke downward while refusing to be a suppliant for a coronet. She loves Silverbridge, but she will not force her way into a family that means to repudiate her — she must conquer them first, or not marry him at all. Her patient campaign to win Lady Mary's esteem, and the Duke's grave interview with his future daughter-in-law, put the novel's questions about blood, nation, and worth directly to the test.
