Hundreds of K-Pop idols debut every year, so it's only natural for there to be an overlap in names. In order to stand out as their own person, some idols use stage names that are either completely different or embody their original name in some way. While they promote under a different alias, their groupmates, staff, and family still refer to them by their original name.

While there are a vast number of people with common surnames like Lee or Kim, that's not the case for everyone. Some idols possess extremely rare family names that are hard to come by, even in Korea. Every 15 years, the country conducts a census in order to take note of and track the number of people with the same surname.

Take a look down below to see the 11 male K-Pop idols who possess the rarest family names.

Note: all data comes from the last census conducted in 2015.
