Robert the Strong
The dynastic surname now used to describe Hugh Capet's family prior to his election as King of France is "Robertians" or "Robertines." The name is derived from the family's first certain ancestor, Robert the Strong (b. 820), the count of Paris. Robert was probably son of Robert III of Worms (b. 800) and grandson of Robert of Hesbaye (b. 770). The Robertians probably originated in the county Hesbaye, around Tongeren in modern-day Belgium.
