Research Notes:

The Chronicle of Alberic de Trois-Fontaines names "comites Stephanum de Ultrasagonam et Gerardum Viennensem" as sons of "comes Renaldus [de Burgundia] fratrem comitem Guilelmum" & his wife. "Willelmus Masticonensis comes et Burgundie" donated "abbatiam de Balma" to Cluny by charter dated 14 Jun 1147, confirmed by "Poncia comitissa uxore mea et filiis meis Stephano et Gerardo".

He succeeded in 1147 as Comte de Mâcon. He is also recorded as Comte de Vienne, although ... his influence (and that of his descendants) in Vienne may have been no more than symbolic. “Comes Stephanus...et fratrem meum comitem Gerardum” settled disputes with Charlieu abbey, with the consent of “matris nostræ...comitis Willelmi patris nostri et avi nostri domini Theobaldi de Treva”, by charter dated 28 Oct 1157. “Gualcherius Salinensis dominus” granted “casamentum donni Pontii de Cuisello” to “comiti Girardo et filiæ meæ uxori eius”, by undated charter witnessed by “Hugo de Tramelay conestabulus...” which also refers to a dispute between “Simon de Commarcey” and “comitem Girardum”. Louis VII King of France issued judgment against “comitem Gerardum Viennensem” in a dispute with the church of Mâcon by charter dated 1166. "Stephanus comes Burgundie", on leaving for Jerusalem, donated property to Cîteaux with the consent of "frater meus comes Gerardus et comitissa Joeta uxor mea" by charter dated 1170. Philippe II King of France issued judgment against “Girardum comitem Viennensem” in a dispute relating to Pierre-Pertuis near Vezelay by charter dated 1180.

The necrology of Besançon Saint-Etienne records the death “XVI Kal Oct” of “Gerardus Viennensis comes” and the donations made for him by “Willermus eius filius...Gualcherius dominus Salinensis eiusdem comitis filius”. ¹
