Nicolas Roger de Beaufort
Nicolas Roger de Beaufort (1340–1415) was a son of Guillaume II Roger and Marie de Chambon and a brother of Pope Gregory XI. First destined for the church, he took up arms after his father was captured at Poitiers in 1356.
In 1371 he joined the papal league against the Visconti of Milan, campaigning with John Hawkwood and fighting at Montichiari in 1373. He married Marguerite de Galard around 1370 and Marthe de Montaut in 1396, after his first wife's death.
