document dated 28 March 1098, Suero was then serving Count Raymond of Galicia as armiger or standard-bearer (alférez). There is no other mention of this appointment, although a certain Suero Núñez who was his alférez on 1 May 1096 may be the same person with his patronymic erroneously copied. There is also only one record of Suero's first tenencia, a jurisdictional fief held directly from the crown and at royal pleasure. According to a charter copied into the tumbo (cartulary) of Lourenzá, Suero was governing Vilarente on 28 August 1099. He may also have governed Monterroso, an important fief in Galicia, under Count Raymond. By 1 April 1101 he was a count (comes), the highest rank in the kingdom, bestowed only by the sovereign. During the rest of the reign of Alfonso VI Suero held only one other tenencia: Rábade, where he is known to have been ruling between 23 January and 5 March 1104. Supporter of Urraca Suero married Enderquina Gutiérrez, daughter of Gutierre Rodríguez and an important member of the Castilian aristocracy. On 30 December 1110 she received a grant from Queen Urraca and was styled comitissa (countess). Since women were not granted that title independently but used it only in the case that their husbands were counts, by this time Enderquina must have been married to Suero. On 27 June 1114 the couple made a gift of land at Torre de Babia to a certain vassal of theirs, Pelayo Fróilaz, for his loyal service. It is the first of series of donations between 1114 and 1129 that the couple made displaying their magnificent landed wealth. On 9 February 1116 Suero is cited in one charter as ruling the city and towers of León, the old imperiale culmen (imperial summit). It is probable that he also ruled the surrounding country. He certainly owned property in León, and he may have previously been its count in 1114. He is described as legionensium comes (count of the Leonese), possibly a mere title with no attendant jurisdiction. Over the next fifteen years he appears governing briefly at Gordón, Astorga, Cordove, and, in 1131, in Laciana and Paredes. After the marriage of Alfonso VI's heiress, Urraca, to the King of Aragon and Navarre, Alfonso the Battler, in 1110, Suero consistently supported the queen against her husband. He was one of those who had confirmed Urraca's first act as successor of her husband
