Nana II was born into the gens (clan) Nánabeszter, which possessed landholdings along the river Danube in Central Hungary, in the surrounding area of royal capitals Esztergom and Buda.
His father was Nana I, who is possibly identical with that namesake noble, who served as ispán of the udvornici in Esztergomváralja (a settlement at the foot of Esztergom Castle) in 1184.
[1] Along with several other members of the kindred, Nana II was first mentioned in contemporary records in 1228, when they separated their estate in Nána (present-day in Slovakia) from the landholdings of the cathedral chapter of Esztergom.
By the time of the separation in 1228, Nana and his relatives also possessed domains in the village of Berki in Pest County, which laid in the territory of present-day Érd.
[3] Agnes testified as the seventeenth nun during the investigation phase of the canonization process of St. Margaret of Hungary – daughter of King Béla IV – in 1276.
