Aung San's paternal grandmother was Daw Thu Sa, whose family traced their lineage from the royal family of the Pagan Kingdom through its last king, Narathihapate. Daw Thu Sa had several cousins who had worked within the government of the last Burmese kingdom. One of her cousins, Bo Min Maung, had been the royal treasurer during the reign of King Mindon. King Mindon awarded Bo Min Maung the title of "Mahar Min Kyaw Min Htin", an honorary title similar to knighthood given to those who are not close relatives of the Burmese royal family. He had a reputation for having a gentle and soft personality.
