Your paternal lineage may be linked to many Indian ethnic groups

Haplogroup O1b1a1a is thought to have arisen in India, roughly 25,000 to 40,000 years ago, and is present in many Indian ethnic groups today. The Indian subcontinent holds four major language groups, called Austro-Asiatic, Dravidian, Indo-European, and Tibeto-Burman. Haplogroup O-M95 likely originated in Indian Austro-Asiatic populations. Its early members carried both the O1-M95 haplogroup and Austro-Asiatic languages further into Southeast Asia through the Northeast Indian corridor. Current research suggests migrating members of O-M95 left eastern India traveling east, through Myanmar, southern China, Vietnam, Laos, Cambodia, and Thailand, and ended in the Andaman and Nicobar Islands. One study found that 100% of a Nicobar Island population belonged to haplogroup O-M95.

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.

What do people with the surname Quach have in common?

Spoiler alert: it's complicated. People with the same last name are usually no more genetically similar than a randomly sampled group of people from the same population. That said, people with the same surname are more likely to have similar ancestries than randomly sampled individuals. The reason is the tendency of people with similar cultural or geographical backgrounds to preferentially mate with one another. That's why people who share a surname may be more likely to share traits and tendencies in common than people within the general population.
