Your paternal lineage may be linked to many of the Massim groups of Papua New Guinea

Haplogroup O2a is prevalent among Massim ethnic groups, including the populations of Airara, Nomanby, the eastern tip of the mainland, the Trobriand Islands, Gawa, Woodlark, the Laughland Islands, and western Calvados. While Papua New Guinea has been inhabited for over 50,000 years, the Massim may have arrived in the last 2,000 years. Today, these populations remain connected through a traditional island trading system called the Kula Ring. Under this exchange system, residents ensure that goods that are only available on some islands, but that are vitally needed in other islands, are shared among the island populations. Only Massim men participate in the Kula exchange system, and it is common for men to be away from home for months at a time when trading with men from other islands.

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.
