Life Seindon Mibaya was born as Shin Thet in 1840. She was the eldest daughter of Le-bo U Sai and Duchess of Ahrlarkatpa, the younger sister of Chandra Mata Mahe, Queen of the South Royal Chamber, who was the mother of King Mindon. Therefore, she was a maternal cousin of King Mindon. She had a younger sibling, Tabe Prince. She was granted the appanages of Sale and Ta Lok Myo when she became the queen consort. She did not bear any issue.
