The traditional historiography goes, in accordance with the inscription on her tomb, that Angelina was the daughter of a Count 'Juan' (i.e. John, János, Ivan, István, etc.
[1] At present it has been proposed that she was a girl of Greco-Serbian origin, a daughter of John Uroš, count of Thessaly and titular Emperor of the Serbs, Greeks, and Bulgarians.
Her sister Maria married the ambassador Payo González de Sotomayor, after having been exiled away to his holdings in Galicia, and later going to France, because the king considered that such romantic involvement was inappropriate for those entrusted with the protection of the ladies during their return trip.
The married Angelina and Diego moved to live in Segovia, specifically in a house which is still preserved today located in the neighborhood of San Juan de los Caballeros.
Later, when the convent of Santa Cruz passed under the patronage of the Catholic Monarchs, her remains were transferred to the Church of San Juan de los Caballeros in the same city.
