Places of note

  • Yanguas (later part of the lordship): Tie in 1200 not pinned.
  • Enciso: Tie in 1200 not pinned.

Where the sources disagree

  • Rodrigo Díaz's tenancies of Calahorra, Jubera and Nájera, and later Soria and Logroño, belong after 1201 and after Diego López's death (1214), not to 1200.

Evidence: Lords' dates are known only from scattered references; who acts for the lordship in January 1200 is inferred.
