Four years later, returning from the fields, Jeanne accompanied by her parents and her brother Déziré were captured by Hadjoutes marauders, who handed the family over as hostages to Emir Abdelkader. He offered the teenage girl as a slave to his friend the sultan of Morocco Abd al-Rahman bin Hisham. He in turn offered her to his son Muhammad bin Abd al-Rahman. 
She was converted to Islam under the name Dagia and enterred the 'Alawi harem as the slave concubine of Prince Muhammed. The following year, in 1837, Muhammed chose to manumit and marry her. 
Shortly after the defeat of Sidi Muhammad by Marshal Bugeaud, during the Battle of Isly on 14 August 1844, Jeanne gave birth to a son.
Muhammad bin Abd al-Rahman allowed her to make contact with her family. She was permitted to visit France on the occasion on Exposition Universelle (1855). She used the visit to make contact with her birth village in France, and also performed a pilgrimage to Chissey.
