Victor Philip Ferrero Fieschi, Prince of Masserano

He was the son of Victor Amadeo (1687–1743), 5th Prince of Maserano, and Juana Irene Caracciolo y Ruffo (1697–1721), from a well-known Neapolitan family.

Victor Philip entered the Spanish Army at the age of 13, served in Italy in 1742 under Montemar and had reached the rank of in Lieutenant general by 1745.

At the same time, he had to try to put a stop to the English usurpations in the Americas, and to agree the details of the return of Manilla to Spain after the British occupation of Manila (1762–1764).

He always acted in full agreement with Grimaldi, maintaining with him not only the usual diplomatic correspondence, but also a continuous exchange of confidential letters.

Fulfilling the orders of his Court, he signed in London with the Earl of Rochford the declaration of 22 January 1771, which satisfied a large part of the English claims.
