Antoine was the 8th ggson of Louis IX of France and was a cus to his wife Jeanne D'Albret, Queen Of Navarre. Jeanne D'Albret was the 9th ggdaughter to Louis. There was alot of Blue Blood or families that married into each other. Its quite interesting. Louis IX children are Philippe III and Robert of France. Hope you can understand this.
