The Gesta Consulum Andegavorum records that "Torquatus sive Tortulfus genuit Tertullum", recording that he was granted property by Charles II "le Chauve" King of the West Franks...

The Gesta Consulum Andegavorum records the marriage of "Tertullus nobilem dux" and "ducis Burgundiæ filiam nomine Petronillam". The Chronico Turonensi names "Ingelgerius comes Andergavensis", the couple's son, as "nepos Hugonis Ducis Burgundiæ". The Gesta Consulum Andegavorum names "Ingelgerius…filius eius Fulco cognominatus Rufus", recording that "Hugo Dux Burgundiæ, filius alterius Hugonis" was "ex parte matris suæ [Fulco] consanguineus". The context suggests that "matris suæ" refers to Foulques, although according to other sources the connection was through the mother of Ingelger. No other record has been found of any dukes of Burgundy who could have been related to Petronilla... ²
