Biography
Vertron is a stronghold belonging to the Allonville family since the 11th century. Besides the hamlet of Vertron, it is made up of those of Les Entonnoirs, Les Brissets and Les Étangs, in the parish of Montacher. The d'Allonvilles collect 100 pounds on seigniorial rights, lease the woods, ponds and land. They also touch the tithes and the champarts. This land brought them 2,684  pounds every year until the Revolution. He was a Knight of the Ordre du Roy, like some of his ancestors. On 16 September 1570 King Charles IX of France gave a notice to Sieur d'Oysonville that the knights of his order were appointed into their company and informs him that he has sent Sieur de Clervaux the collar of the said order to present to him. Francis II played a fairly important role in the Italian wars, in particular the tenth (1552–1556) and the eleventh (1556–1559), under Henry II (1547–1559) and he is also known as one of the Catholic leaders during the Wars of Religion. He was deputy of the nobility of Étampes to the Estates General of 1560 in Orléans and to the Estates General of 1588–1589 in Blois. He was also a Gentleman of the King's Chamber.
