[385] Mademoiselle de Mercocur was the only daughter and heiress of Philippe Emmanuel de Lorraine, Duc de Mercocur, the brother of Louise de Lorraine, Queen of Henri III.

By that monarch he was appointed Governor of Brittany, but in 1589 he revolted against him, and persisted in his rebellion until 1598, when he entered into a treaty with Henri IV, by which he bound himself to bestow the hand of his daughter, and the reversion of his government, upon Cesar de Vendome, a condescension by which he subsequently felt himself so much disgraced that he withdrew from the Court and engaged in the war of Hungary.

Pining, however, to see once more his wife and daughter, he was on his way to France for that purpose, when he was attacked by fever at Nuremberg, where he expired in March 1602, at the age of forty-three years.
[386] Don Pedro de Toledo, Constable of Castile, and general of the galleys of Naples, was a relative of Marie de Medicis, whose grandfather, the Comte de Medicis, had married Eleonora de Toledo, the daughter of the Viceroy of Naples.

He was, moreover, a grandee of Spain, and one of the most confidential friends of Philip III.
