Komitat Neutra
Béla IV donated Chrenóc (; today part of Chrenovec-Brusno) in Nyitra County to Matthew I in 1243. One year later he acquired the estate of Pruszka (today: "Pruské, Slovakia") in Trencsén County, which previous landowner died without heirs. Later Matthew I exchanged that land to Tunig, Pozsony County. According to a royal charter issued in 1249, Béla IV formerly also donated Racsic (; today part of Nitrica) to Matthew, who was already dead by that time. There is no source about his inherited possessions, thus data on his four sons' inherited estates also does not exist. Consequently, he did not initiate his family through the establishment of oligarchical power with land acquisitions, he just marked its direction (from the ancient estates of the genus in Fejér County to northwest).
