François Louis was the second son of David de Büren (1614-1659) and Marguerite de Bonstetten (1619-1685). He became a page for Charles I Louis, Elector Palatine in Heidelberg. François Louis was very well thought of and his future seemed very bright. In 1657 just before he would be given the title of écuyer (squire) he fell gravely ill and died, he was only 19.
