Singyan Thakhin (Burmese: ဆင်ကြန်သခင်), also known by her title Kinwun Mingyi Gadaw (Burmese: ကင်းဝန်မင်းကြီးကတော်; 1793 — 1862[1]), was a Burmese court official who served as the Amaydawkhan Gadawgyi (အမေးတော်ခံကတော်ကြီး) in the royal court of King Mindon. She was the first wife of Kinwun Mingyi U Kaung. She was granted the appanage of Singyan and was therefore known as Singyan Thakhinma (lit. 'mistress of Singyan').[2]
According to the royal chronicles, she was a lady-in-waiting during the reign of King Bagyidaw. Some historians claim that the Singyan Princess was a minor queen consort of King Pangan.[3] As a queen of the fourth rank, she was granted the appanage of Thanlyin.[4]
In another account, she was said to be married to a royal justice U Bo who was granted the title of Minhla Thiri Kyawhtin during the reign of King Tharawaddy. She became a widow when U Bo died.[5]
In 1851, Prince Mindon ordered to the 59-year-old widow, Singyan Thakin, to married a 30-year-old the Clerk of the Royal Treasury (ရွှေတိုက်စာရေး), Maung Kaung, and they served together at the royal court.[6] [7]
There was no issue by their marriage.[8] Kinwun adopted the two sons of the brother of his second wife, Shwe Me.[9] [10]
