Robert II, Count of Hesbaye
Robert II (Rodbert, Chrodobert) (died 12 July 807) was a Frankish nobleman who was count of Worms and of Rheingau and Count of Hesbaye around the year 800. He is the earliest-known male-line ancestor of the French royal family called the Capetians (including the Valois and the Bourbons), and of other royal families which ruled in Portugal, Spain, France, Luxembourg, Parma, Brazil and the Kingdom of the Two Sicilies.
Robert of Hesbaye is the earliest ancestor of the dynasty known as the Robertians, who is identified with some confidence. His son was Robert III of Worms, and his grandson was Robert the Strong. He was eventually the great-grandfather of two Frankish kings, Odo and Robert, both of whom ruled the kingdom of Western Francia.
One of Robert of Hesbaye's male-line descendants was Hugh Capet, the founder of the French royal dynasty which ruled France continuously until 1848, although with a brief interregnum caused by the French revolution and the First French Empire. A junior line has held the Spanish Crown since 1700; the current monarch Felipe VI and his family are direct descendants. Various cadet branches of the Capetian dynasty have ruled other countries including Navarre, Italian states prior to unification, and others.
Robert was probably the son of Thuringbert of Worms and Rheingau and thus a grandson of Robert I, Duke of Neustria (c. 697–748).[according to whom?] An alternate theory has him as the son of Robert, son of Thuringbert.[according to whom?]
It is also possible that Ingerman of Hesbaye and Cancor were brothers of Robert of Hesbaye, and Landrada, mother of Saint Chrodegang, archbishop of Metz, is likely to have been his sister.[according to whom?] Ermengarde, the wife of emperor Louis the Pious was probably his niece.[according to whom?]
