His only son, Edoardo Agnelli, was born seven months after the couple's wedding, in New York on 9 June 1954. Gianni gave up trying to groom him to take over Fiat, seeing how the boy was more interested in mysticism than making cars (he studied religion at Princeton University and took part in a world day of prayer in Assisi). Edoardo, who seemed burdened by the mantle of his surname, committed suicide on 15 November 2000 by jumping off a bridge near Turin; Gianni himself joined police at the scene. Edoardo never married, but he had one son (born out of wedlock in 1973) who was not recognized by Gianni Agnelli. The Agnellis had only one daughter, Countess Margherita Agnelli de Pahlen. She is the mother of John Elkann, Lapo Elkann and Ginevra Elkann. She has five other children from her second marriage to Count Serge de Pahlen. Maria de Pahlen, Peter de Pahlen, Anna de Pahlen and Tatiana de Pahlen.
