According to Bob D'Aoust's marriage index, the parents of Madeleine are Joseph-Marie D'Aoust and Marie Catherine Chasle Chales. (Yes, this is how the name appears. Maybe it is a typo?)
You might want to contact Bob directly and see if he can give you any more info than this. Just look for any of the replies that he has posted, and use the e-mail address that displays when you double-click on his name. If you provide him your "line" of D'Aousts, he will give you the website address of his marriage lines of the D'Aousts. I noticed that he doesn't have the place of this marriage, so you may want to provide that to him. He is the resident expert, as he has done over 12 years of research on the D'Aoust line and has even published a book on this.
