Rorgon I of Maine

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 Count of Rennes from 819 and of Maine from 832 until his death.

He was a son of count Gauzlin I of Maine and Adeltrude, both of whom are named as his parents in a charter of 839 by Rorgo I to the Abbey of Saint-Maur de Glanfeuil. 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. An Abbot Ingelbert of Saint-Maur-des-Fossés allegedly assisted Rorgon and sent monks including Rorgon's brother Gausbert. Gausbert (Gauzbert) was the name of an Abbot at St. Maur.

Count Rorgon had been a retainer at the court of Charlemagne, with whose daughter Rotrude he had a sexual relationship. The couple had at least one illegitimate child, Louis, Abbot of Saint-Denis, Saint-Riquier, and Saint-Wandrille, who was also chancellor to his cousin Charles the Bald from 841.

Rorgon married a lady named Bilechilde, and had three sons and two daughters:
