According to a charter issued on 22 March 1446 at Somkerék (today Șintereag, Romania), they shared the lands of Somkerék, Sáromberke and Gernyeszeg (today Dumbrăvioara and Gornești in Romania, respectively) among themselves, while also owned jointly the villages of Sárpatak (Șapartoc), Unoka (Onuca), Körtekapu (Poarta), Szekérberete, Rücs (Râciu), Záh and Lőrinctelke (Leorinţa), in addition to parts of Nagydenk, Kisdenk and Mártondenk/Martinesd in Hunyad County (today all belong to Mărtinești commune in Romania).
They handed over the latter settlements to King Matthias in return for Péterlaka (Petrilaca de Mureș) and Körtvényfája (Periș) in 1458, today parts of Gornești commune.
[4] In 1448, Erdélyi simultaneously held the office of vice-voivode and ispán of Torda County for a short time, serving alongside other noblemen.
[6] It confirmed that the Erdélyi brothers remained loyal to the Hunyadi family during the emerging civil war, thus they received land donations after Matthias ascended the Hungarian throne in 1458.
Both of them gained tax exemption of "sheep fiftieth" in 1462, while Nicholas and his adult son Ladislaus also received this privilege in the next year.
