Wer heiratete Argilo?

Bermudo Núñez (died c. 955) was a magnate from León and the first Count of Cea. He appears for the first time in 921 confirming a donation to the Monastery of San Benito in Sahagún from which it can be assumed that he was probably born near the end of the 9th century. A loyal vassal of the Leonese monarchs, he confirmed several royal charters and appears with the title of Count from at least the year 950, governing as a tenente the Cea region from 939 onwards.

He probably played a relevant role in the Battle of Simancas and after this victory of the Leonese troops, collaborated with his brother, Oveco Núñez, Bishop of León in the repoblación of Salamanca.
