Marguerite, Duchess of Rohan

She was the only child of Henri de Rohan, Duke of Rohan and Marguerite de Béthune, a daughter of Maximilien de Béthune. Her family claimed ancestry from the reigning Dukes of Brittany and at the French court, were allowed the rank of Foreign Princes. This entitled them to the style of Highness and other privileges at court.

Appealing to the Queen Regent Anne of Austria, in 1645 Louis XIV issued a certificate that willed Marguerite the right to keep her status, her dignity of a princess, should she marry Henri de Chabot. When the Marquis of Seneterre interrogated her on these matters, she replied: I do not know if I shall be able to decide to marry him, but I do feel that I could not bear it if he married someone else.

Previously, her hand had been asked by Louis de Bourbon, Count of Soissons and cousin of the King Henri IV; she refused. Other candidates included Prince Rupert of the Rhine, the Duke of Nemours, and the Duke of Saxe-Weimar. Eventually, she married Henri in Paris on 6 June 1645. The couple were the parents of six children, four of which would have progeny.

By her marriage, she brought her dowry to her husband as well as all her possessions and titles, with the condition that the children bear the name and coat-of-arms of Rohan only. Later the children decided to call themselves Rohan-Chabot and thereby did not honour the clauses of the marriage-contract.

The marriage of a Rohan to a mere nobleman of no fortune was seen as a mésalliance for the powerful Rohans, one of the oldest families in France. Her husband was created Duke of Rohan in 1648.

Titles she held in her own right were; Duchess of Rohan, Princess of Léon, Duchess of Frontenay, Countess of Porhoët, Marquise of Blain, Dame of Lorges, Countess of Porhoët amongst others.

The ducal peerage of Rohan was re-established for Chabot in 1648. Marguerite, Duchess of Rohan in her own right, as a widow was named guardian of her children by royal letters of 10 June 1655.

She died in Paris on 9 April 1684 at the age of 67.
