Her name is registered in contemporary chronicles and documents for being the lover of prince Alfonso de Castilla, future king Alfonso X of Castile, son of Ferdinand III of Castile and Beatriz de Suabia.
In 1255, Alfonso gave her lands in Louisiana Alcarria which included Cifuentes, Viana de Mondéjar, Palazuelos, Salmerón, Vadesliras and Alcocer. With the collaboration of King Alfonso, she founded the Monastery of Santa Clara de Alcocer in an unpopulated village called San Miguel del Monte within the jurisdiction of Alcocer. From her relationship with Infante Alfonso she had one daughter:
Beatrice (1242–1303), the sole beneficiary of her mother"s estates, married Afonso III of Portugal and was the mother of Denis I of Portugal.
Years later, on July 24, 1276, King Alfonso executed an agreement with Juan González who made a walnut-wood sepulchre with a bas-relief image of Mayor.
The parchment document was auctioned at Christie"s in 2009. The convent, as well as her sepulcher were moved to Alcocer years later.
Her body, which remained intact until the beginning of the 21st-century, disappeared in 1936 along with a polychromed sculpture considered among the best funerary art from the Middle Ages in Guadalajara.
