[1] However, according to the contemporaneous Roger of Torre Maggiore's Carmen Miserabile, Denis, son of Ampud was blinded by Béla IV immediately after his coronation, and he died in captivity in the next year.
[2] Vajay refused the former compliance efforts of "Cepeз" with the Csepel Island, a major royal residence and hunting forest.
This "Comes Dionysius" was referred to as Queen Violant's relative (Latin: affinis domne regine) in contemporary Aragonese documents.
Through the maternal lineage, Denis was the first cousin of Gertrude of Merania, a daughter of Berthold IV and the first spouse of Andrew II of Hungary.
Although Violant was born from the second marriage of Andrew (her mother was Yolanda of Courtenay), thus there was no blood relationship between the queen and Denis of Hungary according to this theory, but the knight clearly belonged to a wider kinship of the royal family.
A certain cleric Charles, who attended the University of Bologna, was referred to as a nephew of Cardinal Stephen Báncsa in 1264, then a son of "Count Denis of Hungary" in 1269.
Bácsatyai argued the inscription on the tombstone of his daughter Elizabeth, where Denis was styled as "comes de Cepeз" is not necessarily identifiable with Szepes County.
He also claimed the mention of kinship relations between Violant and Denis first appear only in the works of 16th-century historian Jerónimo Zurita y Castro.
Kiss analyzed the composition of Báncsa's household (familia) in the Roman Curia, and observed an unusually large proportion of clergy of Spanish nationality, which is due in part to the fraternal relationship with Denis, according to the historian.
[10] Vajay considered Denis was entrusted by the elderly king Andrew II shortly before his death to escort and protect his youngest daughter in the Iberian Peninsula.
[11] Denis is appeared as leader of that Hungarian contingent, consisted of knights and young nobles, which escorted the queen to the Kingdom of Aragon.
Historians identified these lands with Alcudia de Veo and Aín (present-day in the Province of Castellón) which laid on the northern slope of the Serra d'Espadà, and both lordships functioned as the king's preparations for the war along the borders of Aragon and Valencia.
[2] Denis' fiefdoms were confirmed in a perpetual and inheritance right (with tax exemption and free usage of local furnace and mill) on 24 January 1244.
[13] After the reconquest, several members of the Hungarian contingent were granted landholdings, houses and orange groves in Valencia and the surrounding settlements, according to the Llibre del Repartiment.
Denis also became the lord of Crespins and owner of some estates in Xàtiva, in exchange for Alcudia de Veo and Aín, which the king took back for the Crown of Aragon, as it was recorded in the Llibre del Repartiment.
[14] Vajay considered the repossessed estates were of strategic importance in military terms, but were less profitable after the end of the war, thus, the exchange occurred in Denis' favor, and his new lordships were not mere compensation.
For instance, he became a brother-in-law of the reigning viscount Guerau VI and Ramon de Cabrera, the lord of the castle of Anglès.
[15] The marriage produced four sons and four daughters, they adopted the Dionís (Dionisii) surname after their father, which goes back to Hungarian tradition.
[15] According to a document from 25 April 1278, Amor obtained 30,000 Valencian sous for his personal needs and to keep 40 knights in the service of the king, which reflects his high social status.
[19] Gabriel had unidentified daughters, who benefited from the sale of Canals in that year,[19] and a natural son named Peter Lodomer, who was born from an extramarital relationship with Urraca Ximénez de Martes.
