He was the eldest son of Nuño Velázquez and Fronilde Sánchez, daughter of Count Sancho Ordóñez.
From at least 28 January 1090 Nuño"s power lay in the region of Limia. Between 1 April 1101 and 24 October 1102 Alfonso served as the alférez of Raymond of Galicia. Between May 1112 and 1 June 1125 Alfonso held the tenencia of Limia, as had his father.
His importance to Urraca in Galicia is exemplified by the Historia compostellana, which lists him first after Urraca"s son when naming the leaders of the army which she assembled among "all the consuls and princes of Galicia" for making war on Alfonso I of Aragon and Navarre in the spring of 1118.
The only record of Alfonso"s wife is from a document of 5 July 1118 in the archives of Celanova, which also happens to be the first record of Alfonso bearing the title comes (count), the highest title of nobility in the land. His wife"s name appears to have been María.
In 1126 or 1127 he made a grant to Braga Cathedral. He is last mentioned in a document of 18 May 1135.
