Cardinals de Bouillon and d'Estrees, first on account of her name and
nation, and afterwards for more tender reasons. In order to detain her
at Rome, these dignitaries thought of obtaining her an establishment.
She had no children, and almost no fortune, they wrote to Court that so
important a man as the Duc de Bracciano, Prince des Ursins, was worth
