Elisenda had three brothers: Ot, heir to Aitona and a godfather of the future Peter IV of Aragon; Gastó, bishop of Huesca and later of Girona; and Guillem Ramón.

[1] Elisenda's great-grandmother was Constance, Lady of Aitona, an illegitimate daughter of Peter II of Aragon, making her and her husband second cousins once removed.

Just a month after the death of the unhappy queen, he went to obtain a dispensation of consanguinity in the third or fourth grade to arrange new nuptials.

The king endowed the bride with income from Berga, Burriana, Tortosa, Morella, Torroella de Montgri, and Pals, and her brother Ot with the locations of Seròs and Mequinensa.

Jesus Ernest Martinez Ferrando wrote: "Elisenda, for her feminine qualities, for her exquisite religiosity, was the best sedative that the monarch could find in the bitterness of his last years; dialogue with the devoted wife sweetened their hours of spiritual and physical ordeal; it can be said that Elisenda helped James II to die well.

[citation needed] Elisenda eventually became interested in the foundation of a monastery of the Order of the Poor Clares around Barcelona.

Once she expressed this desire, the king hurried to please her, even though there was already Vilafranca del Penedès, a monastery of Poor Clares founded by Blanca of Anjou, his second wife.

At first it was designated to be located at the site of Valldaura, between Cerdanyola and Montcada, but then it was decided on a place called Pedralbes due to the amount of white stone extracted from an existing quarry.

[citation needed] After a year the basic structure of the monastery was done: they could use the cloister, and the church and housing for the nuns were almost finished as well.

She participated actively in the decision making of the religious community and put special emphasis on obtaining several privileges for the monastery.

The tomb of the Queen is a magnificent work of Catalan Gothic that artistically represents the double life of this woman.

From the church, Elisenda is portrayed as a queen wearing her crown, and from the cloister she is dressed as an austere widow or nun.
