[1] She married a man called Arnuwanda, who became Tudḫaliya II's heir, co-ruler, and eventual successor.

[2] The nature of the relationship between Ašmu-Nikkal and her husband Arnuwanda was long controversial, since both are described as children of Tudḫaliya II on their respective seals,[3] ostensibly implying that they were siblings or at least half-siblings.

[6] Ašmu-Nikkal and Arnuwanda I appear to have had several sons: Ašmi-Šarruma, Mannini, Pariyawatra, Kantuzzili, Tulpi-Teššub, and the future king Tudḫaliya III.

[8] Ašmu-Nikkal, great queen of Hatti, seems to have actively participated in the government of her husband Arnuwanda I, and is cited with him in administrative documents and oaths.

[9] Together with Arnuwanda, she offered up prayers to the gods to alleviate the Kaška invasion of the northern portions of the Hittite kingdom.
