The three brothers were granted portions in Maros (with its church dedicated to Catherine of Alexandria) and Szanás in Veszprém County (near present-day Somogyszil, Somogy County) by King Andrew III of Hungary in 1296, 1297 and 1298, which lands were confiscated from Ambrose Szarvasdi, a familiaris of the rebellious Kőszegi family, who, in addition, died without descendants.
The latter took the fortress at Pécs and handed it over to Cantor Nicholas who thus succeeded in prevent Bishop Peter from entering his see and collecting revenues from his bishopric.
Although Archbishop Thomas and Bishop Peter excommunicated Cantor Nicholas, he did not give up his position in Pécs.
Thereafter Bishop Peter mostly stayed in the retinue of the papal legate, Cardinal Gentile Portino da Montefiore.
For instance, he took part in the negotiations between the most influential noblemen of the Kingdom of Hungary and the papal legate in November 1308, and also participated at the coronation of Charles of Anjou on June 15, 1309.
