The family lived in Paris, where Count Jefferson was a managing director of the local branch of the bank Sal. Oppenheim and where she worked at UNESCO's World Heritage Centre. Beginning in 2013, Alexandra and Jefferson lived in Heidesheim Castle, Germany, near Mainz.^[8] The couple announced their intention to divorce in May 2017.^[9]
