Jakó II Kaplon

They are first mentioned in 1249 (albeit without names), when their maternal grandmother Agnes (spouse of the aforementioned Peter) donated her dower to them and her two daughters, Catherine (their mother) and Petronilla.

Peter and Agnes donated another villages – Vinna (Vinné), Zalacska and Tarna (Trnava pri Laborci) – surrounding the aforementioned estates to their daughters still in that year.

[6] The names of Jakó and his brother Andrew first appear in contemporary records in 1258, when their maternal aunt Petronilla bequeathed the right of patronage over the Benedictine monastery of Kána, in addition to her portions in the aforementioned villages, to them in her last will and testament.

[7] Jakó's career, together with Andrew, elevated during the first stage of the so-called feudal anarchy in the 1270s, when various baronial groups fought each other for the supreme power during the reign of the minor Ladislaus IV.

[10] In 1279, Ladislaus IV donated them the fort of Jeszenő (today Jasenov, Slovakia) with the surrounding forest as a "lost heritage" (the estate and the castle were possessed by Joachim Gutkeled prior to that).

At the height of the internal political crisis, when both Ladislaus IV and papal legate Philip of Fermo were imprisoned, Jakó served as Master of the cupbearers at least from January 1279 to July 1280.

[12] During the latter, Jakó and Andrew were involved in a lawsuit with the influential Tekesh kinship over the estate Gelyénes in Szatmár County (near present-day Satu Mare, Romania), which they eventually obtained.

[6] Following the extinction of the Árpád dynasty and the era of Interregnum (1301–1310), Amadeus Aba, as a powerful oligarch, ruled de facto independently the north-eastern region of the Kingdom of Hungary, including Ung County.

[14] Jakó last appears as a living person in contemporary records in October 1311, when donated a possession in Zemplén County of his late son John (I) to his unidentified daughter and his son-in-law Thomas Kendi.
