In this family portrait, the Duke and Duchess have 4 children.
Josefa Manuela is the eldest daughter, and her father holds her hand.

Francisco de Borja stands, playing with the swagger stick of his father like a horse.
He will inherit the title of Duke.
Pedro de Alcántara is the youngest of the 4 children.
