Gunrod
Gundered (; putatively ; sometimes rendered Gunrod or Gunrød) was a Viking warlord, known only from a group of twelfth-century Spanish Latin Chronicles all of which derive from the lost eleventh-century "Chronicle of Sampiro": the "Historia Silense", the "Liber chronicorum of Pelayo of Oviedo" and "Chronica Naierense". In the account of the "Historia Silense": In the second year of his reign (Ramiro III, i.e. 968) one hundred ships of Vikings ("Normani") with their king Gundered penetrated the cities of Galicia and with much slaughter in the lands of Santiago, whose bishop Sisnando perished by the sword. They sacked all  Galicia as far as the "Pirineos montes Ezebrarii". In the third year of their settlement, God, from whom nothing is hidden, brought down his vengeance upon them; for just as they had carried the Christians away captive and put many to the sword, so many ills fell upon them, until they were forced to go out from Galicia. Count Guillelmus Sánchez, in the name of the Lord, and with the aid of the Apostle Santiago whose lands they had devastated, went out with a great army and with divine aid killed all the pagans, including their king, and burned their  ships. None of the people mentioned here, nor the precise places, can be certainly identified apart from Bishop Sisnando Menéndez, though Guillelmus Sánchez might be identifiable as an obscure Galician count of Visigothic descent, , or as William Sánchez of Gascony. This has not prevented speculation about Gundered's identity. Suggestions include that he was one of two sons of the (possibly fictitious) Norwegian king Haraldr inn hárfagri named Guðrøðr in the thirteenth-century Icelandic "Heimskringla"; or that he was a "Sea-King" ("sækonungr"), possibly a cousin or brother of Harald II of Norway.
