[5] Mullissu-mukannishat-Ninua was probably the first person to be buried in the tombs in the Northwest Palace, since her sarcophagus is wider than the entrance to the room housing it and must as such have been constructed before the surrounding vault.

[5] She is the only Neo-Assyrian queen for which information concerning her family background and origin are known; her funerary inscription identifies her as the daughter of Ashur-nirka-da’’inni, the "great cupbearer" (šāqiu rabiu) of Ashurnasirpal.

Michael Roaf suggested in 1995 that Ashur-nirka-da’’inni's appointment as great cupbearer and eponym holder coincided with Mullissu-mukannishat-Ninua's marriage to Ashurnasirpal and that she was thus the king's second wife (after an unknown earlier queen) and married to him only briefly, but this is speculative; it is equally likely that Ashur-nirka-da’’inni held the position of great cupbearer significantly earlier and that him being honored as eponym holder was a late development.

This idea has been discarded by recent scholars, however, given that the seal was located in a bronze coffin in the same room, not inside Mullissu-mukannishat-Ninua's sarcophagus.

[11] The inscription curiously appears to identify her as the queen of both Ashurnasirpal and of his son and successor Shalmaneser III (r. 859–824 BC).

[21] During the looting, a part of the great stone lid of the sarcophagus was smashed, which over the centuries allowed dust to drift into the grave.
