3. Paduka Sri Sultan Ahmad Tajuddin Shah, son of the late Sultan Mansur Shah. The latter was afterwards called “Almarhum Kota Lama Kanan”. His former name was Raja Ahmad, and the length of time he was on the throne is unknown. This Sultan died at Jolong, and was called “Almarhum Muda” and his grave is at Geronggong, in the mukim of Pulau Tiga, Lower Perak District. The grave of this Sultan is in the land owned by a Javanese named Haji Muhammad Saleh. His tombstones were beautifully engraved by Acheen people. One of the two tombstones is broken and cannot be mended and therefore both stones should be renewed.
