Your paternal lineage may be linked to the Cham

One of the many populations harboring members of haplogroup O1b1a1a1a1 is the Cham ethnic group, a group of people who speak Austronesian languages in Mainland Southeast Asia. Austronesian languages make up a language family that is extremely large and widespread, comprising over 350 million people on islands such as Madagascar, Easter Island, and many others. However, Austronesian languages are less common on mainland Asia, with a notable exception being the Chamic language. Research suggests that ancestors of the Cham people migrated from Southeast Asian islands to the mainland around the year 500 BCE, and that early Cham populations quickly began mixing with indigenous southern Vietnamese populations. As a result, the Chamic language now has words that were borrowed from languages spoken by indigenous Vietnamese people. It is likely that an ancestral Kinh population was one of the populations that mixed with the Cham people shortly after their migration to mainland Asia.

Your maternal lineage may be linked to the ancient people of the Indian subcontinent

While Haplogroup M is widespread throughout South and East Asia, it is more diverse on the Indian sub-continent than anywhere else in the world. The high degree of diversity of M in India is likely tied to its ancient arrival here nearly 50,000 years ago. In addition to M2, which is found throughout the subcontinent, there are dozens of haplogroups branching off of M that exist in India. These branches are often connected to specific regions, tribes, or ethnic groups. For example, haplogroup M18 is found among the Oraon peoples of eastern India and Bangladesh, while haplogroup M41 is common among the Pardhan speakers of eastern India, and haplogroup M31a can be found on the Andaman Islands, just off the southeast coast of India.
