Qui est sorti avec Guillaume IX de Hesse?

Guillaume IX de Hesse-Cassel puis Guillaume I^er de Hesse (en allemand : Wilhelm IX von Hessen-Kassel dann Wilhelm I^er von Hessen) (3 juin 1743 - 27 février 1821) est landgrave de Hesse-Cassel de 1785 à 1803 puis prince-électeur de Hesse de 1803 à 1806 et de 1813 à 1821.

Karoline von Schlotheim (6 July 1766 - 7 January 1847) was a German noblewoman who was the third and final mistress of William I, Elector of Hesse from 1788 until 1811.

Rosa Dorothea Ritter (29 July 1759 – 13 January 1833), also called Rosette Ritter and Baroness of Lindenthal after 1783, was a German woman who was the second mistress of William I, Elector of Hesse from 1779 until 1788. She was an ancestor of the Barons of Haynau.

Charlotte Christine Buissine or Buissinne (4 April 1749 – after 1781) was a Frenchwoman who was the first mistress of William I, Elector of Hesse from 1775 until 1778.

She was the daughter of a Hanau civil servant, the farmer Henri Buissine, and his wife Charlotte Varlut, both of French descent. Prince William was then and until 1786 regent in the County of Hanau, then a secundogeniture of the Landgraviate of Hesse-Kassel.

Issue:

With William I, Elector of Hesse, Charlotte had four children, three of whom lived to adulthood:

• Wilhelm of Heimrod (16 July 1775 – 6 January 1811)
• Karl of Heimrod (19 July 1776 – 13 May 1827)
• Friedrich of Heimrod (9 August - 30 October 1777), died in infancy
• Friedrich of Heimrod (1778 – 3 September 1813)

The illegitimate children of Charlotte and William received - like their mother - the titles Freiherr/Freifrau/Freiin von Heimrod, the place of birth of the firstborn child.

She was replaced by Rosa Dorothea Ritter as William's second official mistress.

In 1781, she married Christian Friedrich Dietzsch in Friedberg, Hesse.
