William Henry Schofield in his time (1895) could write little of this figure, noting that other than being the author of
Le Bel inconnu, "he is only known to us otherwise as the author of a song song, one stanza of which is preserved in
Le Roman de la Rose ou de Guillaume de Dole. On the assumption that the heraldic device assigned to the title character of
Le Bel Inconnu (namely
lion ermine on field
azure) had belonged to the poet, it was the discovered he belonged to the Bâgé family, and not the rivaling Beaujeu clan. There are two Renauds fitting the time period, the stronger possibility being Renaut/Renaud, Seigneur de
Saint-Trivier (fl. 1165–1230). That song author's place of origin was "Rencien", could be a scribal error for "Rencieu" () or
Rancy which is close to Saint-Trivier, the domain inherited by the junior sons of this clan, providing additional corroboration for the identification. Renaud of Saint-Trivier was the third son of Renaud/Raynald III, Seigneur de
Bâgé (1153–1180) who in the year of succession in 1153 had battled with Count Macôn,
Humbert lord of Beaujeu, and others (they were resentful of resentful of Renaud III's dominion over the Bresse region). In 1180 the father died and was succeeded by the poet's elder brother Ulrich III, but Ulrich's son Guy by his first marriage predeceased him (in 1215), so that when Ulrich died in 1220, the lordship was succeeded by his son by his second marriage, Renaud/Raynald IV, who became seigneur de Bâgé et de Bresse. == Explanatory notes ==
