  General Notes:

PIERRE de Savoie ([1047/49]-killed 9 Aug 1078). "Hubertus comes" donated property to the canons of Saint-Jean and Saint-Urse by charter dated 1040, signed and consented to by "Oddo, Amedeus comes, Aymo Sedunensis episcopus, Brochardus filius Huberti comitis, Petrus marchio filius Odonis marchionis et commitissæ". "Oddo et uxor mea Adalaicis…et filii mei Petrus Admedeus et filie mee" donated churches to Oulx by charter dated May 1057. He succeeded his father in 1060 as PIERRE I Comte de Savoie, Aosta, Maurienne et Chablais, Marchese di Susa , under the regency of his mother until 1064. "Dominus Petrus Marchio filius quond. bonæ memoriæ Oddonis marchionis…cum domina Adheleida comitissa matre sua" signed a charter dated 31 Jul 1064. "Adelegida…comitissa" donated property to Pinerolo, for the souls of "domni Manfredi marchionis genitoris mei et Adalrici episcopi Barbani mei et Bertæ genetricis meæ et…domni Odonis marchionis viri mei", by charter dated 8 Sep 1064, signed by "Petri, Amedei, Vitelmi qui Bruno vicecomes vocatur…Henrici qui vocatur Marchio…". "Domna Adelaida comitissa filia…cum filiis suis Petro et Amedeo" donated property to Novalesa, for the soul of "mariti sui Oddonis", by charter dated 16 Jul 1078. He appears to have come to a violent end.

m (1064) AGNES d'Aquitaine, daughter of GUILLAUME VII "Acerrimus/l'Aigret" Duke of Aquitaine, [GUILLAUME V Comte de Poitou] & his wife Ermésinde --- ([1052]-after 18 Jun 1089). Her parentage and marriage are confirmed by the charter dated 26 Oct 1078 under which "Agnes filia quondam Guillelmi Pictaviensis comitis et relicta…marchionis Petri" donated property to Pinerolo. Agnes´s father is not identified more precisely in any document which has so far been identified. However, the reference to "quondam" in the 26 Oct 1078 charter excludes Guillaume VIII Duke of Aquitaine who was still alive at that date. Duke Guillaume VI, who died in 1038, is also probably excluded, as Agnes would have been over 26 years old at the time of her marriage if she had been his daughter, which seems improbable as noble girls often married when aged 12 to 15 at the time. Duke Guillaume VII is therefore left as the most likely candidate to be Agnes´s father. According to Europäische Stammtafeln, Agnes was the widow of Ramiro I King of Aragon. Szabolcs de Vajay states that the wife of King Ramiro was the daughter of Guillaume VI Duke of Aquitaine not of Duke Guillaume VII, although no source is cited to support this. From an onomastic point of view, it is surprising that a daughter of Duke Guillaume VI would have been named Agnes. The name appears only in the family of the Comtes de Poitou after the third marriage of Duke Guillaume V with Agnes de Mâcon [Bourgogne-Comté], whereas Duke Guillaume VI was the son of Duke Guillaume V's first marriage. "Adalegida cometissa filia Maginfredi marchionis et relicta quond. Oddonis idemque marchionis" donated property to the monastery at Taurini, in the presence of "domne Agnetis comitissæ, filiæ Wilelmi comitis et relictæ quondam Petri marchionis", for the souls of "Maginfredi patris, Adalrici Astensis episcopi patrui, Berthæ matris et Petri marchionis filii predictæ comitissæ Adalegidæ", by charter dated 4 Jul 1079. "Adalasia comitissa cum nuru sua Agneta et filia eius Agnete" donated property to "ecclesiæ S. Mariæ…Astensis episcopatus" by charter dated 18 Jun 1089.

Comte Pierre I & his wife had [three] children: Agnes, [Alix] and [Berthe]. 1
