Rorgon I or Rorico(n) I (also Rorgo or Rorich; died 16 June 839 or 840) was the first count of Maine and progenitor of the Rorgonid dynasty, which is named for him.
He was a son of lord Gauzlin I of Maine[1] and Adeltrude, both of whom are named as his parents in a charter of 839 by Rorgon I to the Abbey of Saint-Maur de Glanfeuil.
[2] Between 819 and 832 Rorgon became count of Maine and at some point, possibly at the bidding of his wife Bilechilde who may have owned the property, undertook to restore the Abbey of Glanfeuil.
[4] Count Rorgon had been a retainer at the court of Charlemagne, with whose daughter Rotrude he had a sexual relationship.
[5] The couple had at least one illegitimate child, Louis, Abbot of Saint-Denis, Saint-Riquier, and Saint-Wandrille,[5] who was also chancellor to his cousin Charles the Bald from 841.
