Mireille Mathieu was born on 22 July 1946 in Avignon, France, the eldest daughter of a family of fourteen children; the youngest brother was born after she moved to Paris. Her father Roger and his family were native to Avignon, while her mother Marcelle-Sophie (née Poirier) was from Dunkirk. She arrived in Avignon in 1944 as a refugee from World War II after her grandmother had died, and her mother went missing. Roger, with his father Arcade, ran the family stonemason shop just outside the Saint-Véran cemetery main gate. The Mathieu family have been stonemasons for four generations. Today the shop is named "Pompes Funèbres Mathieu-Mardoyan", owned and managed by her sister Réjane's family.
