Nesthäkchen is Annemarie Braun, a Berlin doctor's daughter, a slim, golden blond, quintessential German girl.

[1] Nesthäkchens Jüngste describes Anne Marie's life as her youngest child, Ursel, grows up and marries.

Brother Hans’ son, a poor student, is about to graduate and does not want to study medicine, contrary to the wishes of his father, but wants to be a farmer like his admired Uncle Klaus.

The difficult situation between father and daughter escalates angrily for a time, but Annemarie smoothes the waves and devises a compromise: Ursel joins the bank, but takes singing lessons from an aging opera diva.

Since her apartment is too big for her and old Hanne, her cook, she takes in travelers, among them two rich Brazilian siblings, Milton and Margarida Tavares, children of a coffee plantation owner.

Numerous letters home describe Ursel’s new life, and at the end of the story she becomes the mother of twins Anita and Marietta, each named after their grandmother Annemarie.
