The meaning of So
1. Korean (Sŏ): written 서, in Chinese characters 徐, meaning ‘slow’. Although there are two Chinese characters for the Sŏ surname, one of these is very rare and can be discounted (there are only about two hundred people in Korea who use this rare character). Some records indicate that the more common character for Sŏ has as many as 165 clans, but only eleven of them can be documented. The first recorded ancestor of the Sŏ clans seems to be a Shilla figure named Sŏ Shin-il. According to some legends, the rulers of the Old Chosŏn kingdom (died 194 BC) were driven from power by the Wiman Chosŏn and settled in the Ich’ŏn area. The Sŏ clans are among the descendants of these ancient rulers. About fifty percent of modern members of the Sŏ clans live in the Kyŏngsang provinces or in Chŏlla South province.

Your paternal lineage may be linked to the Khasi-Khmuic groups of Southeast Asia
Haplogroup O2 is very common among several ethnic and linguistic groups in northeastern India, East Asia, and Southeast Asia. Haplogroup O2 is particularly common among Khasi-Khmuic groups of Southeast Asia. It is possible that the Khasi, one of the Khasi-Khmuic ethnic groups, represent a genetic link between South Asian populations and Southeast Asian populations that diverged from each other during the massive human migration from Africa. During this migration 50,000-70,000 years ago, modern humans left Africa and began moving eastward, along the southern coast of Asia. These migrating humans very quickly reached South and East Asia, using the Western Indian corridor to enter India. They later used northeastern India as a corridor to reach Southeast Asia and Oceania. The Khasi people, among whom haplogroup O2 is common, may descend directly from this ancient human migration that is responsible for the peopling of much of the world.
Your maternal lineage may be linked to the Han
Members of haplogroup D are found in both northern and southern Han Chinese populations at low to moderate frequencies. 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.
What do people with the surname So 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.
