 An obscure reference to a Pere Riu among some "jongleurs" from Puigcerdà near Foix in October 1344 may be to Peyre, but it is impossible to tell.The Pedro who was a "jongleur" of the count of Foix, mentioned in an Aragonese register of June 1357, may be Peyre de Rius.So may be Pere Ruiç (perhaps an error for Riuç), minstrel of the count of Foix, of July 1368.
