Diego Laínez or Diego Flaínez (d. 1058), Spanish nobleman, father of Rodrigo Díaz "el Campeador".
< Wikipedia > Diego Laínez de Vivar (ca. 1023-1058) was an active childhood in Burgos and was traditionally considered the father of Rodrigo Díaz, known as "El Cid". According to the legendary genealogy of the Champion, Diego was a descendant of Laín Calvo,1 one of the hypothetical two Judges of Castile and of the lineage of Diego Porcelos, founder of the city of Burgos.
According to the < Roderici History >:
This [Lain Calvo] seems to have been the origin of his lineage: Laín Calvo fathered several sons; among them were Fernando Laínez and Bermudo Laínez. Fernando Laínez in turn begot Laín Fernández and Bermudo Laínez begot Rodrigo Bermúdez. Laín Fernández in turn begat Nuño Laínez, and Rodrigo Bermúdez begat Fernando Rodríguez, Fernando Rodríguez in turn begat Pedro Fernández and a daughter named Eylo. Nuño Laínez took this Eylo as a woman and begat Laín Núñez in her. Laín in turn begat Diego Laínez, and this Diego Laínez begat Rodrigo Díaz, the Champion, in Rodrigo Álvarez's daughter.2
If it is accepted that it was El Cid's father, he was married to María, Sancha or Teresa Rodríguez (only the surname of El Cid's mother is known with certainty), who was the daughter of the Count of Oviedo, Rodrigo Álvarez who ruled several estates, including Luna, Torremormojón, Moradillo, Cellorigo and Curiel.3

The second son of Flaín Muñoz, (or Lain Núñez) Count of León around the year 1000, Diego Laínez de Vivar descended from a secondary branch of the Leonese aristocratic lineage of the Flaínez.a He appears documented in a diploma from 1047 in the monastery of San Pedro de Cardeña as Didaco Flaginiz. This document is also confirmed by Nuño Álvarez, a Castilian magnate who considers himself one of the brothers of Rodrigo Álvarez, the probable father of the wife of Diego Flaínez whose name is unknown.
These possessions gave him a status equivalent to that of the middle magnaticia nobility, although it was not enough for him to access the royal curia, because perhaps he was harmed by his alleged collaboration with his nephew Flaín Fernández II in a rebellion against Fernando I that took place between 1061-1065 and that cost him the confiscation of his assets.7 That circumstance would veto Diego However, his son Rodrigo Díaz was accepted at that same time as a member of the entourage of the still Infante Sancho II of Castile, which casts doubt on this hypothesis. It is likely that his apartment in León and the schola regis was due to the fact that he was the illegitimate son of Flaín Muñoz.c
Diego Flaínez died, according to Menéndez Pidal (La España de el Cid, I, p. 127) around 1058, a date accepted by most historians.9

The Historia Roderici names Diego Laínez as son of “Laín Nuñez”. The "Corónicas" Navarras name "Iac Layniç" as the son of "Layn Nuniç". The Nobiliario of Pedro Conde de Barcelos names "D. Diego Lainez, D. Fernando Lainez" as the children of "Lain Nuñez".
“...Didaco Flaginiz” subcribed the charter dated 29 Oct 1047 under which [presumed to be his wife´s uncle] “Nunu Albariz et uxor mea domna Goto” donated the church of Santa María “in riuulo Kabie iuxta terminos de...Burgos” to San Pedro de Cardeña. He captured the castles of Ubierna, Urbel and La Piedra from Navarre, probably after 1054. 1
Diego married doña Teresa Rodríguez DE ASTURIAS, daughter of Rodrigo Álvarez DE ASTURIAS and Teresa LAÍNEZ.

Diego Laínez de Vivar (ca. 1023-1058), infanzón activo en Burgos y padre de Rodrigo Díaz, conocido como «El Cid». Segun la genealogía legendaria del Campeador, Diego era descendiente de Laín Calvo, uno de los hipotéticos dos Jueces de Castilla y de la estirpe de Diego Porcelos, fundador de la ciudad de Burgos.
Casado con María, Sancha o Teresa Rodríguez (solo se conoce con seguridad el apellido de la madre del Cid), que era hija del conde de Oviedo Rodrigo Álvarez de Amaya y nacida de una hija ilegítima del Rey de León.
Fuera del matrimonio, con una campesina tuvo a Fernando Díaz, quien se casaría con una hija de Martín Antolínez, vasallo de El Cid que se enfrentó y venció a Diego González, infante de Carrión.
