Her marriage is confirmed by the charter dated 19 Aug  of "Burchardus sancta Viennensis archiepiscopus et Udolricus frater meus et advocatus meus" granted property "in pago Genevensi…in villa Marischa…a circio Lemani lacus" made "pro remedio animarum…genitore nostro Anselmo sive pro genetrice nostra Aaldui". A series of documents, including this charter, shows that Aldiud had been the mistress of Conrad I King of Burgundy, probably before her marriage to Anselm, and that she gave birth to Burchard Archbishop of Lyon by the king. This is established as follows. Firstly, the Chronicon Hugonis names the king´s son, the archbishop of Lyon, as "Burchardus, Rodulfi regis frater, Conradi ex concubina filius". Secondly, Burchard´s mother´s name is confirmed as Aldiud by a charter dated 14 Feb 1005, which records that "Burchardum Lugdunensem archiepiscopum" donated property "in loco Oponlongis infra comitatum Ottingen" which he had "ex patre matris suæ Aldiud quod rex Chuonradus ei præbuit" to Anselm bishop of Aosta. Thirdly, the name of the father of Anselm Bishop of Aosta is confirmed as Anselm in the charter of Rudolf III King of Burgundy for Romainmotier dated [1001/02], which was witnessed by "…Anselmus episcopus Augustensis…Anselmus pater Anselmi episcopi…". Fourthly, a charter dated 1 Nov 1002, noted by Rivaz in his compiled index of Burgundian charters, confirms that Anselm Bishop of Aosta and Burchard Archbishop of Lyon were brothers: "Burchard archévêque de Lyon et abbé de Saint-Maurice" [Aldiud´s illegitimate son] granted property "dans les comtés de Valais et de Vaud" to "Gauslin", with the consent of "Anselme son frère évêque d'Aoste et prévôt de ladite abbaye". Fifthly, Anselm and Aldiud were also parents of Burchard Archbishop of Vienne and Udalrich his avocatus, as shown by the charter dated 19 Aug  referred to above. The conclusion therefore is that the only way in which Burchard Archbishop of Lyon could have been the brother of the three brothers Anselm, Burchard and Odalric is if they shared the same mother, who gave birth to them by different fathers. Aldiud´s relationship with the earliest counts of Savoy is indicated by Rodolfus Glauber who describes Burchard, son of Count Humbert "aux Blanches Mains", as nepos of Aldiud's illegitimate son. This relationship is explained by Count Humbert's wife being the legitimate daughter of Anselm and Aldiud, as shown below. The Chronicon Hugonis specifies that the king´s son Burchard was appointed archbishop (dated to 978) when still a child. This presumably dates Aldiud´s relationship to the King Conrad to [965/70], which is probably before she married Anselm.
Aldiud married Conrad I "the Peaceful" DE HAUTE-BOURGOGNE King of Upper Burgundy, son of Rudolph II DE HAUTE-BOURGOGNE King of Upper Burgundy and Bertha VON SCHWABEN. (Conrad I "the Peaceful" DE HAUTE-BOURGOGNE King of Upper Burgundy was born in 922-925 in Arles, Bouches-Du-Rhone, Provence-Alpes-Cote-d'Azur, France, died on 19 Oct 993 in Vienne, Angers, France and was buried in cathédrale Saint-Maurice, Vienne, Angers, France.)
Aldiud also married Cte Anselm II DES EQUESTRES. (Cte Anselm II DES EQUESTRES died before 1019.)
