Your paternal lineage may be linked to the Han Chinese

Haplogroup O-Page23 has been found in several populations of the Han Chinese ethnic group. The ancestors of the Han, called the Huaxia, lived in the upriver basin of the Yellow River 5,000-6,000 years ago. As agricultural technology improved, the Huaxia spread east and south, and became the Han Chinese. Over the last 2,000 years, there have been three major migrations of the Han southward. The first of these migrations occurred during the Jin Dynasty from 317 to 420 CE, when nearly one million people moved south. A second migration occurred during the Tang Dynasty, after the An-Shi Rebellion, between 755 and 762 CE. The last migration occurred during the Southern Song Dynasty, from 1127 to 1297 CE, when nearly 5 million people migrated southward. The Pinghua, a branch of Han in which haplogroup O2a2b1a1 is particularly common, may be descendants of indigenous minority groups that adopted Han culture during one such major migration event.

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 Diep 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.
