Jean d'Arclais et Pierrette de Montbosq This shield circa 1360

The first known name of this line is that of Jean d'Arclais husband of Pierrette de Montbosq. Their son Jean II d'Arclais inherited the estate of Château de Montbosq bought by his mother, Pierrette.

Jean II stood out for his devotion to the service of the King of France in his long battles against the English during the 100 years war. He was rewarded by the office of the King's pannierier in June 1402.

On February 8, 1427, he was was authorised by King Charles VII, to withdraw to his lands in Saint-Martin-de-la-besace for a rest from life spent under arms. As the English still had control of this part of the country, the King admits that he puts himself under the authority of the English without removing his protection!

Prince Honoré V Grimaldi of Monaco This painting was executed circa 1800

Prince Honoré-Gabriel was born in Paris on May 14, 1778, the eldest son of Prince Honoré IV of Monaco and Princess Louise Felicite Victoire d'Aumont, Duchesse de Mazarin et de La Meilleraye.
In 1819, when his father passed away, Honoré-Gabriel became the Sovereign Prince of Monaco as Honoré V and inherited a Principality beset with problems. At once a member of the French Parliament and a Sovereign, he picked up on the project of his grandfather to diversify economic resources and encouraged the installation of factories.
History has tended to record Prince Honoré V as a very unpopular and autocratic monarch, but, in reality he was quite progressive. He wished to help his people sincerely and had great sympathy for the poor. His reaction to seeing beggars on the streets was to form state-owned industries and put them to work. Some of the industries he set up included a lace factory and a hat factory. He also had them put to work on farm cooperatives as citrus orchards had long been a large part of the Monegasque economy.

Officer on the staff of Marshal Grouchy This painting was executed circa 1815

He enlisted in a French cavalry regiment when he was 20 years old and worked his way up through the ranks by his own merits until he became an officer on the staff of Marshal Grouchy. He was an exemplary soldier and was cited for his bravery many times. He was wounded in the arm at the great Napoleonic victory in the battle of Hohenlinden which prevented him from seeing action at Austerlitz.

He did serve with great distinction at the battles of Jena with Marshal Murat's cavalry corps. Marshal Grouchy recommended him for the star of the Legion of Honor, relating that the Prince had taken a handful of cavalry and forced the surrender of an entire enemy battalion.
