San Esteban de Gormaz
Sancha was a great-granddaughter of Rodrigo Díaz de Vivar, called the Cid. It has been argued that the author of the "Poema de mio Cid", perhaps Per Abbat, was patronised by the Lara family and that the "Poema" can be read as a work of "escarnho e mal dizer" ("shaming and cursing") against the Laras' enemies, the Castros (represented in the epic by the "Infantes de Carrión"). The town of San Esteban de Gormaz, nearby where the daughters of the Cid were beaten and abandoned, was also the site where the Laras, led by Pedro's father, hid the young Alfonso VIII in 1163; and the favourable light shone on Avengalvón, the last Muslim ruler of Molina (which fell to the Christians shortly before 1138), may reflect his relationship with the later Lara rulers of the same.
