An abandoned baby left at the Gardners' doorstep in Marie-Grace and the Orphans. Marie-Grace named him for the street he was found on, St. Philip Street. He has blue eyes and brown hair, and his skin is light enough that they cannot determine if he is a person of color. Mr. Hearst, a manager of a local plantation, claims that he is the child of a runaway slave and therefore is the legal property of the plantation. The Gardners care for him until he can join Holy Trinity's orphanage. Cécile and Marie-Grace dress him in fancy clothes so he will be accepted. Marie-Grace also finds comfort in caring for Philip because he reminds her of her brother Daniel, who died four years previously.
