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 many people of Europe and Asia

Most of Europe's most common haplogroups, including H, J, T, V and U, are offshoots of R. Some, like U, were involved in some of the earliest migrations to Europe, while others spread from the Middle East with the dawn of agriculture. These groups spread east as well, reaching Central Asia and India first with early farmers and then with Iron Age migrants. In East Asia, R gave rise to the dominant haplogroups F and B. Members of just one branch of B, B2, migrated from Siberia to the Americas after the peak of the Ice Age 18,000 years ago, where their descendants are found today. However, no other branches of R have been found in the indigenous people of North and South America.

What do people with the surname Tay 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.
