She was originally from Rougiers but lived in Genoa for a long time, where she met Lanfranc Cigala, who wrote about her in some songs.
These and Lanfranc's vida form the major source of information about her life.
She is also the addressee—la flor de cortezia, the flower of courtliness—of an anonymous canso, "Quan Proensa ac perduda proeza" (when Provence had lost prowess), which bemoans her long stay in Genoa.
Guillelma's only surviving piece of poetry is a partimen, "Na Guillelma, maint cavalier arratge", with Lanfranc,[1] in which he posed her the dilemma: Dame Guilllelma, a band of weary knights abroad in the dark, in most dismal weather, wished aloud in their own tongues that they might find shelter.
[2] Guillelma answered that l'autre fes ben ("the other did well") for "the man who keeps his word is held in much / higher esteem than he whose plans are in flux."
