^(Hmannan Vol. 2 2003: 214) says Kyaswa was a younger brother of Thihathu of Prome. If he was a full brother, then his mother would be Shin Mauk. However, he could have been a half-brother.
^Standard chronicles Maha Yazawin and Hmannan Yazawin are internally inconsistent. (Maha Yazawin Vol. 2 2006: 163) and (Hmannan Vol. 2 2003: 214) say that Kyaswa died, having been in office for 39 years, and was succeeded by Saw Yan Naung in 685 ME (29 March 1323 to 28 March 1324). But the chronicles (Maha Yazawin Vol. 1 2006: 280) and (Hmannan Vol. 1 2003: 403) themselves say that Yan Naung became governor of Prome after Kyawswa I of Pinya had become king in 704 ME (29 March 1342 to 28 March 1343). (Per contemporary inscriptional evidence (Than Tun 1959: 124), Kyawswa I became undisputed king on 29 March 1344. Thus Yan Naung most probably became governor only on or after 29 March 1344.)
