[3] It is presumable that Herman also participated in Stephen's civil war against his relative Koppány in the following year, similarly to other German knights, for instance Vecelin and brothers Hont and Pázmány, ancestors of the Hont-Pázmány kindred.

The narration of the medieval chronicles about the kindred's origin is unverifiable, but historian János Karácsonyi argued, the Hermáns definitely settled down in Hungary ahead of the Héder and Hahót clans, also of German origins, who came to the kingdom in the middle of the 12th century and their lands laid in the "gyepűelve", a mostly uninhabited or sparsely inhabited area beyond the Austrian border, while the Hermáns were granted estates in the inner parts of Transdanubia.

[4] Other historians considered, knight Herman was a descendant of the Diepoldinger kinship and its cadet branch, the House of Raabs which ruled the Burgraviate of Nuremberg in the 12th century, until their extinction around 1191, as both families used the depiction of dragon in their coat-of-arms.

Contrary to other descriptions, both the Gesta Hunnorum et Hungarorum and the Illuminated Chronicle (which utilized magister Ákos' work) remained short-spoken while presented the history of the Hermán clan.

[5] According to historian Attila Zsoldos, the terms "quite high nobility", "free men" and "poor in lands" prove that the Hermáns originally belonged to the social status of royal servants who owned possession and was subordinate only to the king.

By the end of the 13th century, the use of the expression ceased, and the "royal servants" merged into the nobility of the kingdom, including the Hermán clan.

Zsoldos referred to a royal charter, which mentioned a Swabian "free man" Kaal, who also escorted Gisela to Hungary in 996 and settled down in Sopron County.

In 1255, comes Dés was granted a land of "three plows" in Körmend to finish its tower, part of the fortified western border system.

Herman's brother was comes Pousa, the most illustrious member of the senior branch during that time, who served as a judge in the court of Queen Maria Laskarina in 1265.

Rubinus, who served the kings of Hungary as a "brave" and "loyal" soldier since the 1260s, was a son of a certain Herman, and had two brothers, Feldricus and Charles.
