Villalobos

The heir of the Osorio, the old comital kin of the Tierra de Campos (Osorio Martínez held Mayorga, Melgar, Benavente and Villalobos), and so of the Flaínez line.

He sits at Villalobos between Benavente and Villalpando, makes gifts to Sahagún, and by 1214 has 'all the land of the Cea'. Through his mother he is half a Galician Limia; through his wife a Froilaz.

Who he is

Name
Rodrigo Pérez de Villalobos
Title

Born
Not pinned
Family
Son of Pedro Arias de Limia and Constanza Osorio, daughter of Count Osorio Martínez (killed at Lobregal, 1 February 1160, by Fernando Rodríguez de Castro, who had married and repudiated Constanza). The Osorio descend from the Flaínez counts of the Leonese plain (general genealogies, not checked here). Wife Teresa Froilaz, very probably daughter of Count Froila Ramírez. Kin: his uncle Gonzalo Osorio (tenant of Villalobos 1170), who with Constanza is credited with the fuero of Villalobos; Aldonza Osorio, builder of San Juan del Mercado at Benavente. The lordship later passed to his cousin Fernando González de Villalobos.
