It is plausible the clan possessed the initial ancient landholdings around Tétény in Central Hungary (present-day Budafok-Tétény, a southwest district of Budapest), including Sóskút and Tordas.
[2] Croatian historian Antun Nekić considered that Abraham was the son of Marcellus II and not his brother.
[10] Marcellus participated in King Andrew's royal campaign against the Principality of Galicia in 1211, functioning as one of the commanders of the Hungarian army.
[5] For his faithful service, Marcellus was granted landholdings and estates across the Drava (including the extended lordship of Peker or Pukur in present-day Badljevina and the surrounding Osuvak), which he tried to expand by purchasing.
[11] It is possible that Marcellus was present when Andrew II and Leszek the White, High Duke of Poland in Szepes (today Spiš, Slovakia) in the autumn of 1214, where they arranged the marriage between Coloman of Galicia and Salomea, and their alliance against regent Vladislav Kormilichich.
[15] Marcellus and Abraham were involved in a lawsuit over the land Toplica (present-day a borough of Daruvar in Croatia) near their ancient area Peker along the namesake river in 1232.
