Daimon was born around 1850, the only son of Audoa and Edaganuwe.[1] He was married three times and had eight children with his first wife, Eibiaun. His eldest son Deireragea went on to become Chief of Anibare District.[1]
An unusually tall man at 6'4", he was involved in Civil War between the north and south of the island, leading the northern fighters. Daimon became a Chief in the late 1880s, and when Germany occupied the islands, he acted as an intermediary due to understanding of English.[1]
When Head Chief Aweida died in 1921, Daimon was chosen as his successor.[1] He remained in post until his death on 21 October 1930 aged 80,[2] after which he was succeeded by Timothy Detudamo.[3] His grandson Hammer DeRoburt became the first president of independent Nauru in 1968.[4]
