This is the aunt of a friend of mine. The family is from Singapore. They are part of an ethnic group called the Pernakans, a Southern Chinese group that moved to Malaysia ~600 years ago for some reason, possibly due to overcrowding in Fujian or worse, the terrible wars that periodically raged through the region.
Chinese groups have been leaving from this part of Southern China for a very long time now, especially in the last 200 years. In the past couple of centuries, this part of China has become very crowded. Possibly as a result, wild and vicious wars periodically raged through the area, sometimes killing 100,000’s of people. If you study Chinese history, you will hear about these wars a lot. It is not uncommon to read that invaders conquered several large cities and exterminated the whole populations of perhaps 300,000 people, men, women and children. This is how the Chinese have often fought wars. Chinese wars are unbelievably vicious and savage.
The Pernakans moved to Malaysia, and over time, bred in with Dutch and Portuguese and to a lesser extent British Europeans. All three were colonists in the region. I believe that they were Min speakers, but their Hokkien has gotten so changed, in particular from massive borrowings from Malay, that these languages in general are no longer intelligible with Amoy or Taiwanese Hokkien Proper.
Most Pernakans now are somewhat Eurasian, Chinese crossed with Dutch, Portuguese and sometimes British. The Pernakans had their own patriarchal culture and were known as very hard workers, often at manual labor type jobs like farming, timber harvest are working on rubber plantations. They committed little crime and had very orderly societies. The European colonists marveled at their high level of civilization. They did keep slaves, but they probably treated their slaves better than any slaves have ever been treated, and in many cases, slaves were freed.
Over time, most Pernakans also bred in with Malays. Pernakans are now a Chinese/Malay/European race, but the Asiatic tends to be prominent over the European in the stock. The mixing of cultures over 600 years in Malaysia resulted in some very interesting fine cuisine.
Many of these Chinese migrated to Singapore, where they, along with Teochew speakers (another Min group) and a large group of Cantonese Chinese, form what is known as the Singaporean Chinese, one of the wealthiest and most economically advanced ethnic groups on Earth. There is still a division of labor in Singapore, with Chinese on top, Malays on the bottom, and Southern Indian Dravidian speakers in between. Nevertheless all three groups are substantially mixed by this point. Most Chinese have Malay blood, and a lot of Malays have some Chinese in them. Malays and Indians are now intermarrying quite a bit. There is some ethnic conflict but not a lot possibly due to the wealth and everyone being so mixed.
Although this woman has a somewhat archaic phenotype (note prognathism), these archaic types are fairly common in Southern China. Many can be seen in the mountains of Yunnan Province. The archaism may be due to incomplete transition from Australoid -> Mongoloid, as the transition happened much later in Southern China than in Northern China, and prominent Australoid types were common in the far south of China only 3-4,000 YBP.
I also believe that this woman may be admixed with Caucasian. And I think the Malay admixture is quite clear. Perhaps I am mistaken, but I think I see some Vedda influence here. That would not be unusual, as Malays were Veddoids only until quite recently, and the Senoi are Veddoids to this day. The Mani Negritos are also still extant.
The transition in Malaysia went from Australoid Negritos (Mani) and Orang Asli -> Australoid Veddas (Senoi) -> Paleomongoloid Southeast Asians (modern Malays). The Malays appear to be aware of this transition, as they state that the Mani and Orang Asli are their ancestors. The bloodline of the Orang Asli goes back 72,000 YBP, so this group has been present in Malaysia since the very first Out of Africa groups, and their archaism is about on a par with the Andaman Islanders, another Australoid group which is also the remains of some of the earliest OOA groups.
