D. Rodrigo Rodríguez de Lara (Rodríguez), señor de Peñalba, Quintanilla y Traspinedo - Wife?

I was trying to find a source in English for this Rodrigo's wife. All I found was the Medlands link that says:

RODRIGO Rodríguez de Lara & his wife ---. According to Salazar y Acha[1136], she was SANCHA Rodríguez, daughter of RODRIGO Fernández de Toroño & his wife Aldonza Pérez. "Domnus Gundissaluus Roderici maiordomus domini regis et uxor mea donna Sanctia" donated the church of San Martín de Villa de Rey to the bishopric of Palencia by charter dated 1 Dec 1202[1137]. "G. Roderici et uxor mea Santia Roderici" granted administration of the hospital at Carrión to the bishopric of Palencia by charter dated 1209[1138].

That's not the same wife he's connected to here on Geni, so is their an English translated source for the wife he is connected to? I don't want to add the wrong connections to my person tree and end up claiming undocumented connections. Plus, if the wife is incorrect, the pathways on Geni are wrong as well.

Thanks in advance for any clarification on his wife.
