He was the eldest son of Martín Flaínez and Sancha Fernández. Throughout his career he was closely associated with his brothers Pedro and Osorio Martínez. All three Martínez brothers met their ends on the battlefield. Martín Flaínez is known to have donated a meadow, money, and some candles to the monastery of Santa Eugenia de Cordovilla because the monks had performed a successful exorcism on the young Rodrigo.
