Infante Philip Peter Gabriel was born early in the morning of 7 June 1712, at El Escorial in Madrid, the King's official residence, three years after the death of his elder brother and namesake, Infante Philip Peter, who had died aged sixteen days.
By Christmas Day 1719, Philip was already very sick. His father arranged for his burial a few days before his death on 29 December 1719. Philip was buried in El Escorial complex.
The generations indicate descent from Carlos I, under whom the crowns of Castile and Aragon were united, forming the Kingdom of Spain. Previously, the title Infante had been largely used in the different realms.
