Career
Agnes herself was Countess consort of Savoy and possibly Queen consort of Aragon. Possible wife of Ramiro I of Aragon
Agnes became a popular name in the House of Poitiers following the marriage of William V, Duke of Aquitaine to Agnes of Burgundy. Three Aquitainian women sharing the name Agnes are known to have married Iberian monarchs, and a fourth Iberian consort also named Agnes has been speculated to have been Aquitainian.
Ramiro I of Aragon married a second wife named Agnes, who based on the name is believed to be of Aquitainian origins.
The woman"s parentage is disputed. She may have been daughter of William VI, Duke of Aquitaine or his half-brother William VII, Duke of Aquitaine.
lieutenant is believed by some that Duke William VI died childless, while being son of an earlier wife of William V, he would be less likely to name a daughter for his step-mother. Countess of Savoy
In 1064, Agnes married Peter I, Count of Savoy.
Three children are assigned to Peter and Agnes:
Agnes (c 1066 – after 13 March 1110) married Frederick of Montbéliard and had issue
Alix (died after 21 December 1099) married Boniface del Vasto and had issue.
(hypothesized) Bertha (c 1075 – before 1111) married Peter I of Aragon, a grandson of Ramiro I. The prior marriage of Agnes would have provided the political context for this marriage. Bertha had no known issue. Peter died on July 9, 1078, leaving Agnes a widow.
A charter confirms that Agnes, widow of Count Peter was still alive in June 1089.
