Ong Kee Hui is the great-grandson of
Ong Ewe Hai (1830-1888), a leading Sarawakian merchant and
Rajah Charles Brooke's advisor on Chinese Affairs, and also confidant; grandson of
Ong Tiang Swee (1864-1950), the first Chinese nominated to the
Sarawak Council Negri (Legislative Council) in 1937; and son of
Ong Kwan Hin (1896-1982), a recognised authority on Chinese temples, who was nominated to the
Sarawak Council Negri (Legislative Council) as well. Generations of the Ong family played a prominent role for the Hokkien community in Sarawak. His great-grandfather Ong Ewe Hai was a prominent Kapitan China to the Hokkien community of Sarawak, and a successful businessman in multiple fields. His grandfather, Ong Tiang Swee was Kapitan China, and also President of the Chinese Chamber of Commerce. His father, Ong Kwan Hin was also Kapitan China. Both Ong Tiang Swee and Ong Kwan Hin were the first two Chinese people nominated to the
Sarawak Council Negri (Legislative Council) in 1937. Today, there are
seven roads in
Kuching,
Sarawak named after generations of the Ong family, some by the
Rajah in recognition of their contribution to the community. These include Jalan Ewe Hai (also Ewe Hai street), Jalan Ong Tiang Swee, Jalan Ong Kwan Hin, Jalan Ong Kee Hui, Jalan Hui Sing, Jalan Datin Wee (Ong) Siew Eng and Jalan Ong Hup Leong, a branch road of Jalan Ong Tiang Swee. Ong Kee Hui is also related to
Ong Poh Lim. His great grandfather Ong Koon Tian ( d:1837) was born in Bai Jiao, Fujian, China and left for south-east Asia to make his fortune, at which he was not successful - on his death he left three sons and three daughters impoverished. == Early life ==
