Asporça Hatun was born a Greek-Byzantine noblewoman, but other details abouts her origins are not known. Contemporary rumors said she was a
Palaiologos princess, a daughter, probably illegitimate, of
Andronikos II or
Andronikos III but most modern historians reject this version. Furthermore, it's impossible that Asporça was Andronikos III's daughter, because he was born in 1296 and Asporça had a son around 1310. Byzantine princesses married to Muslim rulers also kept their own names and Christian faith, but Asporça took an Ottoman name and converted to
Islam. Another thesis is that Asporça was the daughter of the Byzantine
tekfur of
Bilecik, who in 1298/1299 was kidnapped by the Ottomans and given to
Orhan, but this woman is now identified as Bayalun Hatun, and if she was Asporça, it would mean that her first child was born over a decade later. ==Marriage==
