House of Béthune

The House of Bethune (French: Maison de Béthune pronounced [mɛzɔ̃ də betyn]) is a French noble house from the province of Artois in the north of France whose proven filiation dates back to Guillaume de Béthune who made his will in 1213.

This family became extinct in 1807 with Maximilien-Alexandre de Béthune, Duke of Sully (1784-1807).

[2] In 1639 André Du Chesne gave a lineage that went back to 1037,[3] but the proven filiation dates back to Guillaume de Béthune called "Le Roux" who made his will in 1213 and died soon after.
