Responding to Rania's interest, the following is the Trencavel agnate lineage, as represented in tables by the Catalan genealogist Armand de Fluvia i Escorsa in two tables (s.v. ?Nimesπ and ?Carcasonaπ) in the multi-volume _Gran enciclopedia catalana_. I present it here as the Trencavel dynasty isnπt easily found in other compilations. Note the odd numbering conventions: numbers are consecutive in various viscounties, applied to repetitions of two names together, not separately. This family, like that of the counts of Toulouse, was dispossessed in the wake of the Albigensian Crusade. I make no claim to accuracy, but itπs a start.
1. Ato I, d. after 867, vc Rouergue ? Aissena; issue:
.... Bernat I, d. after 918, vc Albi, who follows.
.... Bigo I, vc. Tououse
.... Ato I, vc. Toulouse ? Ava (of Auvergne?); their issue:
........ Bernard I, vc. Toulouse
........ Ato II, vc. Rouergue
.... Sicard ==> a quo the viscounts of Lautrec.
