"Airardus dominus Cacenniaci uxore mee Felicitate laudante" donated property to Basse-Fontaine by charter dated 1183, which refers to a donation of "vineam Rufe de Couvegnon" made by "matris mee" (who is unnamed in the document but "Agnes…domina de Chachennaio" is recorded making the same donation in the following charter)[862]. "Airardus dominus Chacenniaci" donated property to Clairvaux by charter dated 1189 witnessed by "Jacobus nepos meus…"[863]. The Chronicle of Alberic de Trois Fontaines names "Erardus de Cacenaio" among those who died in 1191 at the siege of Acre[864]. m firstly MATHILDE, daughter of --- (-[11 Dec 1179/1183]). "Arardus de Chacennaio" confirmed donations to Clairvaux made by "avus meus Ansericus, laudante uxore sua Humbelina", with the consent of "uxore mea Mathilde et nepote meo Jacobo", by charter dated 11 Dec 1179[865]. "Erardus dominus Chacennaii…Mathilde uxore sua" confirmed donations to the abbey of Mores by charter dated 1182[866]. According to Europäische Stammtafeln, "Mathilde or Félicité, daughter of Hervé [III] de Donzy & his second wife Clémence de Bourgogne" was the wife of Erard [I] de Chacenay[867]. The primary source which confirms this parentage and marriage has not yet been identified. As explained in the document BURGUNDY DUCHY NOBILITY, if this parentage of Erard’s wife is correct, it is chronologically more likely that Clémence, her mother, was the first wife of Geoffroy [III] de Donzy. If this is correct, she was MATHILDE [Félicité] de Donzy, daughter of [GEOFFROY [III] Seigneur de Donzy & his first wife Clémence de Bourgogne [Capet]. m secondly FELICITE, daughter of --- (-after 1183). "Airardus dominus Cacenniaci uxore mee Felicitate laudante" donated property to Basse-Fontaine by charter dated 1183, which refers to a donation of "vineam Rufe de Couvegnon" made by "matris mee" (who is unnamed in the document but "Agnes…domina de Chachennaio" is recorded making the same donation in the following charter)[868]. As note above, Europäische Stammtafeln conflates the two wives of Erard [I] de Chacenay into "Mathilde or Félicité, daughter of Hervé [III] de Donzy & his second wife Clémence de Bourgogne"[869]. It is not known whether this is correct, but until more information in other primary sources comes to light it is considered preferable to show Erard as having married two different wives. Erard [I] & his first wife had three children
