Robert the Strong
Hugh's paternal ancestral family, the Robertians, appear in documents that can trace them back to his great-grandfather Robert the Strong (d. 866). His origins remain unclear, but medieval records hint at an origin in East Francia, in present-day Germany, an area then still also ruled by the Carolingians. In particular, Regino of Prüm (died 915 CE) states that Robert the Strong's son Odo was said to be a relative ("nepos") of a Count Meingaud, count of an area near Worms, who died in 892, and there are indications that Maingaud's family used the names Robert and Odo.
