When people start to trace their family history, they often look to their surnames for clues about their origins. Naming conventions vary between cultures. For those of Vietnamese origin, they will have to look at other information: dates of migration and ruling dynasties.

This is because Vietnamese naming conventions are different from those used in other countries. Each child would be given three names: their first name, middle name, and surname. However, surnames were changed depending on which dynasty was in power. Because of this practice, many Vietnamese people had the same surname despite not being related to each other.

Why did Vietnamese people have this practice of changing surnames? Keep reading to find out more about why this happened, and what are the most common Vietnamese surnames.

Vietnamese Names Have Three Parts

In Vietnamese culture, parents traditionally bestow three names to their children: first names, middle names, and last names. The convention of last names became widespread in Vietnam after they were conquered by China. As Vietnam came into contact with different countries, religions, and cultures, surnames from different parts of the world became popular in the country.

This practice of choosing surnames is what sets Vietnam apart. In other cultures, families would keep a unique surname to indicate their unbroken matrilineal or patrilineal descent. But in Vietnamese history, much of the Vietnamese population would change their name depending on who was in power.

Because there are certain family names that are very popular in Vietnam, they cannot be used to accurately distinguish an individual like Western names. If you encounter a three-part Vietnamese name, note that it is the given name (aka the first name) that is commonly used to refer to someone.

While most of Vietnam’s population have one middle name, it is possible for people to have two or more. It is also possible for them to have no middle name at all. This is because it will depend on a family’s naming practices and parents’ preferences.

Such names are typically used to indicate the generation to which a person belongs, especially in a large family. Each family may give a child a specific middle name to mark this. For example, the Mac clan may have two different names to indicate two generations: Mac Nghia and Mac Dinh.

Why Is Nguyen The Most Common Vietnamese Surname?

It is estimated that nearly 40% of all Vietnamese people bear the common last name “Nguyen”. This practice extends to both Vietnam and Vietnamese people outside the country. There are several theories as to why “Nguyen” is the most common surname.

The first theory is that “Nguyen” has its roots in the Chinese last name of “Ruan” (or “Yuen” in Cantonese). During the Northern and Southern dynasties (420-589 A.D.), a large wave of Chinese people with this name fled China for Vietnam to avoid political upheaval. Over time, they assimilated with the local population and created a large group of Vietnamese with the name “Nguyen”.

The second theory points the finger at changing dynasties. General Tran Thu Do (1194 – 1264) overthrew the Ly Dynasty and established the Tran Dynasty by arranging a marriage between his nephew and the Empress Regnant of the Ly Dynasty. After his nephew was crowned, Tran Thu Do became grand chancellor and regent – the de facto ruler of the Tran Dynasty. To consolidate his power, he allegedly forced Ly descendants to change their name to “Nguyen”.

While no reason was given for why Tran Thu Do did this, it was clear why Vietnamese families chose this name during the heyday of the Nguyen Dynasty. When the Nguyen Dynasty took power in 1802, many people with this surname were able to avoid prosecution and receive awards.

The third theory is rooted in the rarity of surnames within Vietnamese lower classes. When the French colonized Vietnam in the 19th century, they held a census across the country. They discovered that most of the lower classes didn’t have a last name. This made it difficult to collect and track population data, so the French gave the name “Nguyen” to anyone who did not have a last name, as the Nguyen Dynasty was the last dynasty in Vietnam.
