Your paternal lineage may be linked to the Han Chinese

Haplogroup O1a is a branch of O-M119, also called O1a. O-M119 and its branches are present in both northern and southern Han Chinese men at low to moderate frequencies, but are most common among the Jiangsu, Shanghai, and Zhejiang southern Han groups. 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, and Han language and culture only expanded into southern China in the last 2,000 years. The spread of Han people and culture from northern to southern China was likely driven by warfare and famine in the north. Members of O-M119 belong to a group that has helped to shape the culture of the world's largest ethnic group.

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 To 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.
