Mendo Páez de Sorred

Mendo Páez de Sorrez or Mendo Páez de Sorred or Men Páez Sorred or Mem Páez Sorred (b. c. 1070 or 1180 - d. c. 1230) was a Spanish noble in the service of the Kingdom of Galicia and by default, also the Kingdom of Castile. He was the head of the House of Sorrez and is best known for founding the House of Sotomayor by initiating the population of the Valle de Soto.

There is some confusion about his birth and death dates. Some sources record Mendo Páez as having been born in 1070. This is the most likely birthdate due to his service to Alfonso VII (Reigning from 1126–1157) and Alfonso VIII (Reigning from 31 August 1158 – 5 October 1214) having been recorded. Other sources put his birthdate at 1180 which is essentially an impossibility given the prior records. His death day which is recorded by some sources as taking place in 1230 is also extremely unlikely.

His paternal grandfather was Garci Méndez Sorrez and his paternal grandmother was Urraca de Ron. His maternal grandfather was Godinho Fafes de Lanhoso, Senhor de Lanhoso and his maternal grandmother was Dórdia Viegas, Senhora da Quinta de Sequeiros.

The House of Sotomayor, founded by Mendo Páez would go on to produce some of the greatest leaders throughout Spanish history. The cadet branch of the family, the House of Méndez de Sotomayor would also rise to power in the 1400s before merging with the House of Haro.

Mendo Páez de Sorrez was recorded as being a Ricohombre in the service of King Alfonso VII of León and Castile el emperador. An award awarded to Mendo after his participation in Alonso VII's Conquest of Almería from the Moors. Mendo Páez also went on to serve King Alfonso VIII of Castile. At some point, Mendo Páez was given the mandate to populate the area of the Valle de Soto in Galicia.
