The Du Han de Martigny were an important noble family of Lorraine, with estates in the north of the duchy.
Louis-Philippe held posts as conseiller d'état, Chamberlain and Grand Veneur under Duke Léopold I, and his daughters were among the court beauties.
In 1731, Jeanne-Thérèse was maid of honour to the Dowager Duchess and Regent of Lorraine, Léopold's widow.
Jeanne Thérèse and her husband Granville appear regularly in the Madame de Graffigny correspondence collated by the Voltaire Foundation at the University of Oxford.
[1][2] She married Granville Elliott, Count Elliott, on 15 March 1735, in Mannheim, but the couple lived in Lorraine after their marriage, where they had one daughter and six sons: Jeanne Thérèse died in Nancy on 7 July 1748 and was buried two days later in the nave of the Notre-Dame cathedral church in Nancy.
