[2] Based on his name Györffy considered that Súr was of Pecheneg origin, who came from a subjugated tribe, which was ordered to settle down along the western border during the Hungarian conquest of the Carpathian Basin protecting and guarding the gyepűelve there.
Györffy argued that Súr was progenitor of the gens (clan) Osl, which possessed landholdings in Sopron County in the 13th century, as his name occurs frequently among members of the kindred.
Along the local stream to the river Váh (Vág), a group of villages – Hegysúr (Hrubý Šúr), Pénteksúr (Malý Šúr; present-day a borough of Kostolná pri Dunaji) along with the nearby river island, and present-day Šúrovce (Súr, which was established by merging four villages – Nagysúr, Nemessúr, Valtasúr and Várassúr) preserved the name of the chieftain and the site of his winter residence.
[1] Based on settlement names in Veszprém and Somogy counties, Györffy considered that Súr was perhaps a member of the ruling Árpád dynasty and belonged to the close relatives of Grand Prince Fajsz.
The Bohemian auxiliary army commanded by Boleslaus I, Duke of Bohemia clashed with a large fleeing group of the Hungarians in the eastern part of Lechfeld on 11 August, where Lehel and Súr were captured near the fort of Ebersberg in Bavaria.
