Gundemaro Pinióliz

Gundemaro Pinióliz (died c. 1012), was a noble from the Kingdom of León, the ancestor of one of the most important Asturian lineages of the Middle Ages, and most likely the great-grandfather of Jimena Díaz, wife of Rodrigo Díaz de Vivar, el Cid.

He was the son of Piniolo Gundemáriz and Jimena Vélaz, daughter of count Vela Núñez and his wife Totilde and sister of count Fruela Vélaz. Gundemaro had several siblings, including a sister, Elvira, married to Vermudo Vélaz, ancestors of count Suero Vermúdez. His paternal uncle was Count Suero, a notorious rebel.

He appears frequently in medieval charters, confirming royal documents as well as in family transactions and donations. In March 976, he confirmed a donation made by his uncle count Fruela Vélaz to the Cathedral de Oviedo, as Gundimaro Pinioli armiger, that is, the standard-bearer of King Ramiro III of León. During a period of fifteen years he served in the curia regis of King Bermudo III of León and in March 996 appears for the first time with the title of count.

Count Gundemaro owned many properties in Oviedo, some purchased and others donated by kings Ramiro and Bermudo. For his baptism, Queen Velasquita Ramírez, possibly his godmother, gave him real estate properties He also owned land and villas in Teverga. With his wife Muniadona he made many donations to religious establishments, especially to the Monastery of San Vicente de Oviedo and to the city's cathedral. He and his wife Muniadona founded several monasteries, including San Miguel de Trevías in 1000 and also the Monastery of Santa Marina.
