Sithu Min Oo

Sithu Min Oo (born c. late 1310s) was the elder son of King Uzana I of Pinya and a longtime claimant to its throne. When Uzana took the throne in 1325 Sithu was technically heir presumptive, but he may never have been proclaimed heir apparent, and the chronicles record no governorship for him, while his younger brother Thihapate ruled Yamethin.

He nonetheless survived the fall of Pinya in 1364 and the founding of Ava in 1365. King Swa Saw Ke of Ava, seeking his prestige, gave Sithu his daughter Minkhaung Medaw in marriage, and through that line Sithu became an ancestor of the Toungoo kings Mingyi Nyo, Tabinshwehti and Nanda.
