Since then, the Macarons des Sœurs have been sold in the city without interruption. When Marguerite died, Marie passed the secret to her niece and the business remained in the family for another three generations. The business was passed to the Aptel family in 1935 and the premises moved from the site of the original pâtisserie to the location it occupies today. Jean-Marie Genot purchased the business in 1991 before passing it, and the secret of the macaron, to his son Nicolas in 2000.
