John III, Count of Auvergne
John III of Auvergne( 1467 – 28 March 1501), Count of Auvergne, Count of Boulogne, Count de Lauraguais, was the son of Bertrand VI of Auvergne and Louise de la Trémoille( 1432 – 10 April 1474), Dame de Boussac, the daughter of Georges de la Trémoille.
He was the last in the line of Counts of Auvergne and Boulogne from the La Tour d'Auvergne family.
After his death Boulogne- sur- Mer was integrated into the royal domain.
William VII the Young of Auvergne
William VII" the Young" of Auvergne was a Count of the region of Auvergne, France during the years 1145 – 1168.
He accompanied the French king, Louis VII, on the Second Crusade.
William was the first Count of Auvergne to be given the title Dauphin( Prince).
What is by convenience called the dauphinate of Auvergne was in reality the remnant of the county of Auvergne after the usurpation of William VII around 1155 by his uncle, William VIII the Old.
The young count was able to maintain his status in part of his county, especially Beaumont, Chamalières, and Montferrand.
Some authors have therefore named William VII and his descendants" counts of Clermont"( although this risks confusion with the county of Clermont in Beauvaisais and the episcopal county of Clermont in Auvergne).
The majority of authors, however, anticipating the formalization of the dauphinate in 1302, choose to call William VII and his successors the dauphins of Auvergne.
Still others, out of convenience, choose to call these successors the" counts- dauphins of Auvergne."
The title of dauphin of Auvergne was derived from William VII's mother, who was the daughter of the Dauphin de Viennois, Guigues IV.
This meant that William VII's male descendants were usually given" Dauphin" as a second name.

She is arguably most famous for saving the life of her nephew, King Charles VI of France, during the disastrous" Bal des Ardents"( Ball of the Burning Men).
