The Princes of Aragon and Navarre were wedded to the daughters of the Cid after the annulment of their marriages to the Princes of Carrion.
In history one of the daughters may have been betrothed or briefly married to Pedro, Prince of Aragon and Navarre. However the daughters actually were married to a nephew of Raymond Berenguer and a Prince of Navarre.
And the Cid said unto Dona Ximena, Now may you without let marry your daughters with the Infantes of Aragon and Navarre, and I trust in God that they will be well and honourably married, better than they were at first.
While yet that messenger of the Soldan of Persia abode in Valencia, tidings came to the Cid that the Infantes of Aragon and Navarre were coming to celebrate their marriage with his daughters, according as it had been appointed at the Cortes of Toledo.
When the Cid knew that the Infantes were coming, he and all his people went out six leagues to meet them, all gallantly attired both for court and for war; and he ordered his tents to be pitched in a fair meadow, and there he awaited till they came up.
Great were the rejoicings which were made in Valencia because of the coming of the Infantes, for eight days before the marriage began.
When eight days were overpast the Bishop Don Hieronymo married the Infantes of Aragon and Navarre to the daughters of the Cid in this manner: the Infante Don Ramiro of Navarre to Dona Elvira, and the Infante Don Sancho of Aragon to Dona Sol.
Then the Infantes made answer, that they prayed God to grant him life for many and happy years yet, and that they thanked him greatly, and held him as their father; and that they would ever have respect to his honour and be at his service, holding themselves honoured by the tie that there was between them.
Three months these Infantes abode with the Cid in Valencia, in great pleasure.
And when they took leave of each other there was not a knight of all those who came with the Infantes to whom the Cid did not give something, horse, or mule, or garments, or money, so that all were well pleased; and he gave his daughters his blessing, and commended them to God, and then he returned to Valencia, and they went to their own country.
And when they reached Salvacanete, the Bishop Don Hieronymo, and Dona Ximena, and Alvar Fanez, and the other honourable men, sent their letters to all the kinsmen and friends of the Cid Ruydiez, bidding them come and do honour to his funeral; and they sent letters also to his sons-in-law, the Infantes of Aragon and Navarre, and to King Don Alfonso.
