Geoffrey of Joinville Isabelle of Joinville Béatrix of Joinville Jean of Joinville Geoffrey of Joinville Simon of Joinville William of Joinville Marie/Simonette of Joinville Héloïse of Joinville
Simon succeeded his eldest brother Geoffrey V as lord of Joinville, who died without children at Krak des Chevaliers in late 1203 or early 1204 during the Fourth Crusade.[2]
In the war of the Succession of Champagne, he fought for his cousin Erard of Brienne-Ramerupt and his wife Philippa of Champagne against the countess-regent Blanche of Navarre and her son Theobald, because the hereditary office of seneschal was not appointed by Blanche. Blanche's forces ravaged the lands of Joinville, and she imposed a humiliating surrender agreement: Simon's fortresses were seized, his eldest son Geoffroy was taken hostage, and he was forced to transfer his ancestral castle at Joinville to his brother, Bishop William, as security for his good conduct.[4][5][6]
Simon of Joinville died on May 1233 and was buried in Clairvaux Abbey.[7]
Family
In the year 1207 Simon married Ermengarde of Montclair,[8] daughter of John of Montclair, and had:
Geoffrey of Joinville, d. 1232,[9] lord of Montclair;[8] married Marie of Garlande[10]
Isabelle of Joinville, lady of Montclair after her brother; married Simon IV of Clermont.[1]
Béatrix of Joinville; married Guermond of Châlons.
Ermengarde of Montclair died in 1218, and in a second marriage Simon married Beatrix (or Beatrice) of Auxonne,[11][12] daughter of Count Stephen III of Auxonne, and had:
Simon of Joinville, lord of Marnay and Gex; married Leonete of Geneva.[12] Much involved with English affairs along with his elder brother Geoffrey.
William (Guillaume) of Joinville, Archdeacon of Salins, rector of Arthinurchir (Ireland) and archdeacon of Besançon.
Marie; married Guighes, Dauphin de Viennois.
Simonette of Joinville; married Jean of Tilchâtel.
Héloïse of Joinville; married Jean of Faucogney. She founded the monastery of Montigny. (This child is not included in source document.)
Important biographical note for the Joinville family. Beatrice of Auxonne had been previously married to Aymon de Faucigny by which they had a daughter, Agnes of Faucigny. Agnes was married to Peter II, Count of Savoy. This made John, Geoffrey and Simon half-brother-in-law to Peter II, Count of Savoy This relationship explains the role played by Geoffrey and Simon de Joinville at the English court and their preferment in England.
Notes
^Smith states Simon's involvement in the Albigensian Crusade was short since Simon returned to Champagne by mid-1210.[3]
