Son of Auguste Emmanuel Roy, merchant and textile industrialist in Reims, and Annette Carcenac (sister of Henry-Gustave Carcenac), he has a sister, Clara, younger than him. His family has been Protestant for generations. He became an associate of "Carcenac & Roy" in 1847, then of "Gustave Roy & Cie" in 1862. At the head of his company "Roy frères", he became famous. He even became a millionaire, which enabled him, to thank his wife, née Berger, for the birth of her daughter Isabelle, after the infant death of one of the eldest, Hélène, to buy the castle of Faÿ.
