His father, Philippe of France, Duke of Orléans, known at court as Monsieur was married to Henrietta of England, daughter of the murdered Charles I of England and the French born Queen Henriette Marie. As such, his parents were first cousins. He had one elder sister, Princess Marie Louise and a younger sister, Princess Anne Marie who was born after his death.
He received the names of his father, Philippe and his maternal grandfather, Charles.
Philippe Charles birth helped to smooth over the difficult relationship his parents had; his father was a renowned homosexual who was under the domination of his long term lover the "Chevalier de Lorraine". Monsieur complained that Henriette (known simply as Madame) flirted with men at court including the king himself. Court gossip claimed that Philippe Charles' own older sister Marie Louise, was the product of Louis XIV's and Madame's flirting.
After the death of the Queen mother, Anne of Austria in January 1666, Louis XIV promised to raise Philippe Charles with his first cousin le Grand Dauphin. At the end of the year, Philippe Charles himself succumbed and died at the Palais Royal in Paris, the grace and favour residence of his parents.
