Boso the Elder

Boso the Elder (c. 800 – c. 855), also known as Boson the Elder, was a Frankish nobleman and the earliest known ancestor of the Bosonid dynasty, a prominent aristocratic family in the Carolingian Empire. He held the title of Count of Turin, and was also associated with the region of Valois. Through his children and grandchildren, Boso became the progenitor of a noble lineage that played a key role in the politics of 9th-century West Francia, Burgundy, and Provence.
