Jacques Goÿon, Count of Matignon (Jacques François Léonor; 21 November 1689 – 23 April 1751) was Count of Thorigny and Matignon, as well as the Prince of Monaco as Jacques I after his marriage to the-then reigning Princess Louis Hippolyte of Monaco. He also contructed the Hôtel Matignon[1]


Life[change | change source]

Born in Normandy, his father was the Count of Matignon, a title that Jacques would inherit in 1675[2] Eventually Jacques would marry Princess Louise Hippolyte Grimaldi of Monaco[3]


Issue[change | change source]

The children of the couple were technically given the surname of "Goyon" after their father however they were sometimes also known under the surname of Grimaldi too.


  1. Antoine Charles Marie Grimaldi (16 December 1717 – 4 February 1718), Marquis of Baux and Count of Matignon.
  2. Charlotte Thérèse Nathalie Grimaldi (19 March 1719 – 1790), nun at the Convent of Visitation at Paris.
  3. Honoré Grimaldi (10 November 1720 – 21 March 1795), successor of his parents.
  4. Charles Marie Auguste Grimaldi (1 January 1722 – 24 August 1749), "Count of Carladés" and of Matignon.
  5. Jacques Grimaldi (9 June 1723 – June 1723) died young.

Name and title[change | change source]

Baptised with the names Jacques François Léonor and using the name Jacques, his surname was simply Goyon. His title was "Comte de Matignon"[4] Therefore the mixture of Goyon and Matignon is unnecessary, and incorrect.


Notes[change | change source]

  1. Today the official residence of the Prime Minister of France
  2. At the death of his father
  3. The daughter of Prince Antonio I of Monaco, and heiress to Monaco
  4. French for Count of Matignon
