Louis XV of France
Louis XV (15 February 1710 – 10 May 1774), known as Louis the Beloved (), was a monarch of the House of Bourbon who ruled as King of France from 1 September 1715 until his death in 1774. He succeeded his great-grandfather Louis XIV at the age of five. Until he reached maturity (then defined as his 13th birthday) on 15 February 1723, the kingdom was ruled by Philippe II, Duke of Orléans, as Regent of France.
Cardinal Fleury was his chief minister from 1726 until the Cardinal's death in 1743, at which time the young king took sole control of the kingdom.
Louise Élisabeth of France
Marie Louise Élisabeth of France (Marie Louise Élisabeth; 14 August 1727 – 6 December 1759) was a French princess, the eldest daughter of King Louis XV of France and his Queen consort, Maria Leszczyńska, and the elder twin of Anne Henriette de France. She married Infante Philip, younger son of Philip V of Spain, who inherited the Duchy of Parma from his mother in 1748, thereby founding the House of Bourbon-Parma. In secondary sources she is referred to also as "Louise Élisabeth of France". She functioned as the de facto ruler of the Duchy of Parma between 1748 and 1759.
