Theories of origin

Her origins have never been concluded. The earliest source mentioning her origin was Domentijan, who said of her: "a great princess, daughter of the Byzantine Emperor Romanos", only Romanos IV Diogenes ruled from 1068 to 1071, making this genealogy impossible.

Mavro Orbini, writing in 1601, mentioned her as a daughter of the Ban of Bosnia. He perhaps mixed her up with the wife of Prince Miroslav, who was the sister of Ban Kulin. However this is not supported by any sources.
Jovan Rajić thought Ana was the daughter of Ban Borić, although this is not supported by any sources. Vaso Glušac believed her to have been the sister of Ban Borić.
Simeon Bogdanović–Siniša claimed that Ana was the daughter of Ban Borić, however, he wrongly thought that Borić and Boris Kalamanos were the same person, thus Ana, based on this assumption, would have been the daughter of Boris.
Justin Popović mentioned her to have been the daughter of Manuel I Komnenos, who after the conflict with Uroš II of Serbia wed of his daughter to him in order to make peace.
Other theories include her being a Hungarian princess or "Frankish" princess.

Through her marriage with Stefan Nemanja, they had three sons and three daughters:

Stefan Nemanjić, Stefan Nemanja's successor.
Rastko Nemanjić, the founder and first archbishop of the Serbian Orthodox Church.
Vukan Nemanjić, Grand Prince of Duklja '' and Grand Prince of Serbia
Jefimija, who married Manuel Doukas, regent of Thessaloniki
A daughter who married Tihomir Asen, and gave birth to Bulgarian Tsar Constantine Tih Asen
