Celebrated, rich and the most powerful woman in the Northwest of the Iberian Peninsula, she has been commemorated by several Portuguese cities.

She was one of the three daughters of Count Diogo Fernandes and of countess Onega (or Onecca) who had been the tutors of the future King Ramiro II of León.

[a] Between 915 and 920 and, most certainly by 926—the year in which they appear together for the first time when King Ramiro II gave the couple the villa of Creximir near Guimarães[7][8][9]— she married Count Hermenegildo González.

She left it in the ownership of countless domains, in an area that coincided reasonably with zones that would integrate the back counties of Portugal and of Coimbra.

The testamentary document in which she makes the donation of her domains, cattle, incomes, religious objects and books to Guimarães monastery, dated 26 January 959,[6][11] was important for verifying the existence of several castles and villages in the region.
