A documented line 路 Singapore
The ancestry of Dr Min Yen Ong, assembled from wills, deeds, probate files, a court judgment and a newspaper death notice. Every person on this page carries the document they came from and a grade for how far that document can be trusted.
The Ong line on one side, the Chua line on the other, meeting at Min's parents' marriage in London in 1974. Colour it by origin, by how strong the evidence is, or lay it out as a conventional chart.
The dashed hollow circles are not missing people. They mark the exact slots where the research stops, which is a gap in the work and not evidence that nobody was there. The most important one sits directly above Min's grandfather, and it is the subject of section 3.
Ong Tiang Wee, known as T W Ong, was a barrister of No. 1 Astrid Hill, Singapore. He died on 24 June 1999, leaving a will dated 19 December 1996 that names six children by two wives and appoints Michael Hwang, then of Allen & Gledhill, as its solicitor.
His son Ong Sin Qui, Min's father, was given the law firm Messrs Laycock & Ong, a firm historically associated with David Marshall, Singapore's first Chief Minister.
Cycle & Carriage was founded in 1899 by Chua Cheng Tuan and Chua Cheng Bok. Their younger brother Chua Cheng Liat, Min's great-grandfather, became managing director in 1940 and chairman in 1949, and won the Mercedes-Benz franchise in 1951. He was not a founder, and this tree says so because the family story rounds it up.
His son Chua Boon Peng, Min's grandfather, chaired the company from 1957 to 1985, and was bankrupted in the Pan-Electric collapse of 1985, when the family properties at Oei Tiong Ham Park were auctioned.
The Chung line of British Guiana, which is where Min's paternal grandmother came from, is entirely untraced above her father. It is the least explored branch here.
And the Khoo connection stops at Khoo Soon Leong of Kuala Lumpur. Any kinship to the well-known Khoo families, Khoo Teck Puat among them, is unevidenced and is not claimed, because assuming is how family trees acquire ancestors they never had.
The chain is Ong Sam Leong › Ong Boon Tat › Ong Tiang Wee › Ong Sin Qui › Min. The generation that was missing is Ong Boon Tat, who built the New World Amusement Park and after whom Boon Tat Street is named.
The document that settles it is the obituary of Ong Tiang Wee in The Peranakan, 1999 Issue 3, which reads: "Born in 1909 Ong Tiang Wee was the eldest son of New World Amusement Park founder Ong Boon Tat and grandson of Ong Sam Leong." The same page records his death on 24 June 1999, the exact date on the probate file, and names the firm Laycock & Ong, which passed to Min's father. Two independent identifiers, in one paragraph.
It does not rest on that alone. Four newspapers between 1933 and 1935 call Ong Tiang Wee the eldest son of Ong Boon Tat. The Straits Times of 1933 and 1935 ties Ong Boon Tat to his mother, Mrs Ong Sam Leong. A 1932 marriage report names his bride as Gertrude Chung Tiam Fook, which matches the principal wife in the 1996 will and could not have been worked backwards from it. And the 1917 inscription on Ong Sam Leong's tomb at Bukit Brown names his grandson 闀疯紳, Ong Tiang Wee, in stone.
One correction travels with it. The obituary dates Ong Boon Tat's death to 1937. The contemporaneous press and his own tomb give 8 July 1941, and this tree follows those.

Where a person rests on family testimony rather than a document, the tree says so and grades them accordingly. Nothing here is marked confirmed on the strength of what someone remembers.
