[2] The earliest dates of his career are determined by the fact that he was a vassal of Gausfred III of Roussillon, who died in 1164 and receives mention in several of Berenguier's works.
[2] It is quite possible that Berenguier was one of the earliest troubadours, and the poems that mention Jaufres (Gausfred) may date as early as 1150.
[6] He may have met Pons d'Ortaffa late in life, and the latter may address him in one of his songs as Senher En Berenguier.
[2] One of his cansos was a model for a sirventes by his contemporary Raimbaut de Vaqueiras, who may have set it to the same tune, Berenguier's most "florid".
The theme which runs through these works cannot be connected to events in Berenguier's life, nor can it be shown that the lady (dompna) of every song is the same person.
