The genealogy of Mingyi Swe and his first wife
Shin Myo Myat (ရှင်မျိုးမြတ်), the parents of King Bayinnaung, is unclear. Though there are no extant contemporary records regarding Bayinnaung's ancestry or childhood, different traditions about the king's genealogy have persisted. According to
Maha Yazawin, the
official chronicle of Toungoo Dynasty compiled two centuries later, Swe was born to a gentry family in
Toungoo (Taungoo), then a vassal state of
Ava Kingdom. His parents were Taungkha Min (တောင်ခမင်း) and Kayenawaddy (ကရေနဝတီ), a descendant of viceroys of Toungoo,
Tarabya (r. 1440–1446), and
Minkhaung I (r. 1446–1451). When he reached adulthood, Swe was married to Myo Myat, a 5th generation descendant of King
Thihathu of
Pinya (r. 1310–1325) and his chief queen
Mi Saw U of
Pagan Dynasty. Despite the official version of royal descent, oral traditions speak of a decidedly less grandiose genealogy: That the couple were commoners from Nga Tha York Provience
Pagan district or Htihlaing village in
Toungoo district, and that Swe was said to be a
toddy palm Toddy Tree climber. The commoner origin story first gained prominence in the early 20th century during the
British colonial period as nationalist writers promoted it as proof that even a son of a toddy tree climber could rise to become the great emperor like Bayinnaung in Burmese society. To be sure, the chronicle and oral traditions need not be mutually exclusive since being a toddy tree climber does not preclude his having royal ancestors. ==Royal household servant==
