Having had proof of their noble qualities, King Emeric received them with open arms and is recorded to have granted them extensive fiefs in various parts of Hungary.

While both authors mention the Nagymartonis' castles in the Iberian Peninsula ("Boiot"), their clashes against the "sultan of Tunis" (plausibly Abu Zakariya Yahya) in Mallorca and Menorca and the coat-of-arms donation derived therefrom, but, the two authors disagree as to why they left Aragon; according to Ákos, the unidentified father of Simon I and Bertrand (or Bertram) rebelled against King James I of Aragon, which resulted his imprisonment.

In contrast, Simon of Kéza writes the brothers embroiled into a conflict with an unidentified count and though they defeated him, the resulting hostility forced them to settle in Hungary.

[3][4] Historian Antal Pór accepted the narration of Simon of Kéza regarding Tota whose marriage with Benedict and her dowry – Nagymarton (or Mattersdorf, present-day Mattersburg, Austria) and Bajót – can be proved in the sources.

Upon Constance's request, King Emeric, attaching it to her dowry, donated all royal revenues of Nagymarton to Tota, exempting the landholding from taxation in 1202.

[6] According to a royal charter of Andrew II from 1221, Benedict was exiled and confiscated all of his estates prior to that (it is possible he participated in the 1209–10 conspiracy against the monarch).

[8] Bertrand mediated the prenuptial agreement between James I of Aragon and Violant of Hungary in February 1233, alongside Pope Gregory IX and Bartholomew le Gros, the Bishop of Pécs.

[10] They [the Mongols] could not take the citadel of the city [Esztergom], because the Spaniard Simon [Symeon Hispanus] manfully defended it with his many crossbowmen.Simon (I) was considered one of the faithful confidants of King Andrew II since the 1220s.

[7] Sometime around the late 1220s, Simon was also granted the land Csenke in Esztergom County (laid near present-day Mužla, Slovakia) by Andrew II.

[8] Following the siege of Esztergom, Simon and Bertrand have completed diplomatic missions several times throughout the year 1242 on behalf of Béla IV in order to seek military assistance and financial aid against the Mongols.

[8] The brothers were granted several lands from the king simultaneously, Gadundorf, Zolonta (present-day a borough of Okoč, Slovakia), Pucyn and Kesző.

[9] In addition to landholdings, Bertrand was made ispán of Szolgagyőr (Galgóc) royal castle (ispánate) within Nyitra County in 1243 (present-day ruins in Hlohovec, Slovakia).

[15] Bertrand married a French noblewoman Ahalyz (or Elizabeth), who was a former lady-in-waiting for Queen Yolanda, the second spouse of King Andrew II.

When Albert I, Duke of Austria launched a massive military campaign ("Güssing Feud"; German: Güssinger Fehde) against the Kőszegis and their allies, the Austrian besieged and captured Nagymarton in May 1289.

In 1291, Andrew III invaded Austria, forcing Albert to withdraw his garrisons from the towns and fortresses, including Nagymarton, that he had captured two years before.

To compensate for the loss of Nagymarton, Simon bought the castle of Kabold (present-day Kobersdorf, Austria) in early 14th century from the Austrian owner, who acquired the fort after the "Güssing Feud" (although, the original proprietors Stephen II then Peter III Csák laid claim).

[27] Together with his cousins (Paul and Lawrence) and brother Nicholas (I), he was granted the duty of Kövesd and the estate Pomogy in Sopron County (present-day Pamhagen, Austria) in 1320 by Charles I of Hungary.

Four years later, in 1324, Paul (I), Lawrence, Nicholas (I) and Denis were granted the land Alramus along the river Leitha for his services in Charles' unification war.

[22] When Andrew Kőszegi attacked the towns of Sopron and Győr, which refused to acknowledge his supremacy, in the winter of 1317, the burghers successfully repelled the offense with the assistance of the troops of Paul and Lawrence.

[29] For their loyalty and bravery, Paul and Lawrence regained the castle of Kabold by Charles in 1319, who seized the fort from the Kőszegis in his military campaign, while the Csáks abandoned their claims over the fortress as a compensation for the loss of Bajót.

His brother Lawrence, who died sometime between 1340 and 1342, and his wife Margaret, a daughter of Austrian lord Wulfing I Haschendorfer, became ancestors of the so-called "German branch" of the Nagymartoni (Fraknói) family.

Michael's grandson, Nicholas (III) "the Hungarian" was granted half portions of the ancient family estates – e.g. Nagymarton, Fraknó, Bajót, Röjtökör and Kabold –, which proved to be a generous deed from Paul, whereas in previous decades their modernization and strengthening was due only to him and Lawrence.

According to a charter from 1353, Nicholas the German was forced to mortgage his four villages to pay off the loan he had taken from a Jewish called Israel from Sopron in order to cover his expenses at his participation in the aforementioned two legations and the Lithuanian military campaign.

For instance, he forced their relative Kónya Szécsényi (his wife Elizabeth Haschendorfer was the sister of Lawrence's widow) to return the estate Ikrény in Győr County to them.

[37] Due to his marriage, Paul (II) foreclosed the mortgage and acquired the castle of Lánzsér (present-day Landsee, part of Markt Sankt Martin in Austria) from the Atyinai family in 1386.

His sons Paul (III) and Nicholas (IV) joined a rebellion against the rule of Sigismund, who, therefore, confiscated the castle of Fraknó from them and handed it over to the Kanizsai family in 1398.

[32] John (II) was lying in his bed in a serious illness in 1400, when mortgaged a half of his portion in Fraknó and its accessories and other already pledged estates to "Christians and Jews" for 2000 Viennese denari.

Palatine Lawrence Hédervári ruled in favor of William who, however, was unable to assert his legal claim because of the emerging civil war in Hungary (1440–1445).

Therefore, the person of Benedict, son of Korlát was also identified with Bánk Bár-Kalán, a powerful lord and alleged mastermind behind the assassination of Queen Gertrude of Merania in 1213.

In his play, the characters of bans Mikhal and Simon of Boioth were of Spanish origin, who were forced to exile to Hungary after their fights against the Moors, but they are constantly longing for home to Hispania.
