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 Han
Members of haplogroups B4 and B5 are quite frequent in both northern and southern Han Chinese populations. The Han people, who all share the same language and similar cultural practices, are the largest ethnic group in the world, with about 1.2 billion people. Historical evidence shows that Han people are descendants of the ancient Huaxia tribes that come from northern China, centered in Zhongyuan, China's Central Plain. The spread of Han people, language and culture from northern to southern China only occurred in the last 2,000 years, and was likely driven by warfare and famine in the north.

What do people with the surname Mo 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.
