At this time he was called Hernistus, but received the name of Poth because he acted as messenger between the Emperor Conrad and the Kings Andreas and Salomon.

In the German language Poth has the same meaning as the Latin nuntius.Medieval chronicles unanimously considered the Győr (also Geur or Jeur) kindred originated from Germany, who came to the Kingdom of Hungary in the first half of the 11th century.

[3] Majority of the historians – for instance, György Györffy, Gyula Kristó and Erik Fügedi accepted the theory of German origin.

He considered the ancestor of the kindred was German knight Győr, who participated in the defeat of Koppány alongside other foreign warriors, and settled down in Western Hungary after receiving royal land donations.

[4] Historian Erik Fügedi claimed the kindred came to the Kingdom of Hungary during the reign of Andrew I (r. 1046–1060) and also accepted the individual Győr as the founder of the clan.

[5] Gyula Kristó accepted the narration of the Illuminated Chronicle, which says Poth (also Pot or Pat) arrived to Hungary during Solomon's rule (1063–1074), but he does not connect him to the Győr kindred; he argues its first member was Otto.

[6] Other historians refused to accept the kindred's claimed German ancestry; late 19th-century genealogist János Karácsonyi did not consider Otto as a member of the clan.

Karácsonyi also emphasized the members of the kindred bore forenames of Hungarian or Biblical origin (e.g. Csépán, Ders, Pousa, Saul or Pat).

He also claims Saul is identical with that namesake abbot of the Dömös monastery, who served in this capacity, when the collegiate chapter was granted privileges and donations by Béla II in 1138.

[15] Sometimes in the middle of the 12th century, ispáns Alexander – it is possible, he is identical with that noble, who was mentioned by the last testament of lady Színes in 1146 – and Seraphin owned the land of Lébény, which then became a royal property.

According to Norbert C. Tóth, Béla III confiscated the estate, because they supported his younger brother, the pretender royal prince Géza in the early 1170s.

[19] Csépán and Pat, alongside other pro-Emeric lords, were able to retain his political influence after the coronation of Andrew II in 1205, because the new royal needed their assistance.

For instance, Pat was granted the village of Hof (Chof) in Moson County by the king in 1208, for his "fidelity" and "tireless strength of probity".

[21] Csépán was also granted two royal lands in Moson County: Szombathely and its customs duties and Balogd by Andrew II in 1209, not long before his assassination.

[23] For his participation in the military campaign against Halych, Pat was granted the marsh of Kopács (present-day Kopačevo, Croatia) and its surrounding three fishponds in Baranya County.

Since members of the kindred's next generation never gained such influence as their fathers, therefore Zsoldos argues that Pat, the last living son of Stephen I, has finally become disgraced for his participation in the 1214 coup attempt.

[26] Still in 1232, Palatine Denis obliged a local noble Peter, son of Maurice to pay damages of 43 silver denari to Pat II, because he previously plundered and devastated his inherited lands of Hof (Chof) and Menyhárt in Moson County.

[28] Conrad, a contemporary of chronicler Simon of Kéza, who referred to him by name in his work, initially belonged to the courtiers of Béla IV; he appeared as Master of the stewards in the court of queen consort Maria Laskarina in 1253.

After that Béla confiscated Conrad's landholdings in Moson and Pozsony counties, in addition to the Óvár Castle and the patronage of the Lébény monastery.

[31] Following Ottokar's invasion to Northwest Hungary in April 1271, Stephen V relocated the capital of Moson County to Conrad's seat Óvár Castle.

[35] His son James was a supporter of Andrew III, but his efforts to protect his lands against the Kőszegis remained unsuccessful, as their dominion gradually expanded into the region Baranya.

[38] Charles I retook the castle of Kéménd in 1316 and handed over to James' two living sons, Nicholas and Conrad III, ancestors of the Gyulai (Geszti) and Kéméndi noble families, respectively.

In 1226, brothers Seraphin and magister Saul, both sons of Somos (or Csamasz), sold ten mansiones from their property in Monyorókerék (present-day Eberau, Austria) to the abbot of Lébény.

[41] He served as archdeacon of Sopron by 1256, when his branch had mortgaged certain lands in Somogy County – for instance, Bajom – to brothers Mojs and Alexander (ancestors of the Dárói noble family), but were unable to ransom them.

[41] In 1279, the chapter of Győr recorded that John, son of Seraphin inherited the half of Gesztence (formerly belonged to Moson Castle) after Saul's death around 1262.

[41] As mentioned above, historian Norbert C. Tóth claims Saul, the first known member of the Szerdahely branch was a direct descendant of 11th-century nobleman Otto and his (adopted?)

Due to the fragmented data from this period, local historian Péter Tímár considers, only Ders I from his branch, who survived the Mongol invasion and its catastrophic consequences.

[46] A document from 1258 proves that Ders also had interests in Győr County: in that year, he and his sons Stephen and George had a negotiation over the income of a vineyard in Tényő with the abbot of the Pannonhalma Abbey.

Historian Pál Engel claimed clan members Demetrius and Julius, who were involved in a legal case within the kindred and supported the Szerdahely branch, were the sons of Stephen.

Its last scion Mihály died sometimes before 1622 (as in that year, his widow married Gabriel Movilă, a former prince of Wallachia, who spent his exile in Transylvania).
