Nine key facts, one pattern: most of what’s known comes from fan-compiled profiles rather than official sources, so some details remain unconfirmed.

Is Martin from CORTIS British?

No — Martin is not British. He was born in Canada and holds dual South Korean-Canadian nationality. According to Kpop Profiles (fan wiki), his father is Canadian and his mother is South Korean, which explains his mixed heritage. Some fans wonder about the name “Martin” sounding Irish or British, but the name itself has Latin origins and is common across many cultures — it doesn’t indicate British nationality.

What is Martin Cortis’s ethnicity?

Martin is of mixed ethnicity: his father is Canadian and his mother is South Korean, making him South Korean-Canadian. Kpop Profiles lists his birthplace as Songpa-gu, Seoul, South Korea, but also notes he lived in Ottawa, Canada for about 1.5 years. An Instagram post (fan account) states he was born in Canada, creating some ambiguity about his exact birthplace. What’s consistent across sources is his dual nationality.

Is CORTIS Martin half white?

This is unconfirmed. While his father is Canadian, no official source has specified his father’s ethnic background. Canadian can mean many ethnicities, so calling Martin “half white” would be speculative. The safest description remains South Korean-Canadian, as stated by Kpop Profiles and MyDramaList (fan database).

The implication: Martin’s background reflects the increasingly global nature of K-pop, where multinational idols are becoming more common. For fans curious about representation, he’s one of several mixed-heritage idols debuting in the 2020s.

How old is Martin CORTIS?

Martin was born on March 20, 2008, making him 17 years old as of 2025. This is consistently reported by Kpop Profiles and Instagram fan accounts. He debuted at age 17 on August 18, 2025, which is relatively young but not unusual for K-pop — many idols debut in their mid-to-late teens.

Is Martin the oldest CORTIS?

This is not confirmed. CORTIS has five members: James, Juhoon, Martin, Seonghyeon, and Keonho, according to Wikipedia. While Martin is the leader, leadership in K-pop groups doesn’t always go to the oldest member. Without official birth dates for all members, it’s impossible to say whether Martin is the oldest or not.

What this means: Martin’s age places him in the younger cohort of 2025 debut idols, but his leadership position signals that BIGHIT Music sees exceptional potential in him.

Did Martin from CORTIS finish high school?

According to Kpop Profiles, Martin passed the high school equivalency exam, meaning he did not complete traditional high school but achieved an equivalent qualification. The same source says he studied at Seoul Joongdae Elementary School and Karak Middle School before pursuing his idol training.

At what age do they graduate high school in Korea?

In South Korea, students typically graduate high school at age 18 or 19, depending on their birth month and whether they started school on schedule. Since Martin was born in March 2008 and turned 17 in 2025, he would normally be in his final year of high school or just graduating. Passing the equivalency exam allowed him to focus on his trainee career without attending regular school.

The pattern: Many K-pop idols take the high school equivalency exam to balance training schedules with education. Martin’s path mirrors that of idols like Jungkook of BTS, who also completed equivalency exams.

Who is the leader of CORTIS?

Martin is the leader of CORTIS. This is confirmed by Wikipedia, Kpop Profiles, and Instagram fan accounts. An Instagram post describes him as “the leader, rapper, and main producer of CORTIS,” highlighting his multi-faceted role in the group.

Why this matters: Being leader at debut is a significant responsibility, especially for a 17-year-old. It suggests Martin has strong leadership qualities and likely played a key role in the group’s formation and preparation.

Who are Martin CORTIS’s parents?

Martin’s father is Canadian and his mother is South Korean, according to Kpop Profiles. The same source says he has an older sister. However, their full names and specific identities have not been publicly disclosed, which is common for K-pop idols who often keep family details private.

What is Martin CORTIS’s full name?

Martin’s full name has not been publicly disclosed. He is known mononymously as Martin, which is his stage name. Some sources like MyDramaList list him as “Martin Edwards,” but this is unverified and not confirmed by official BIGHIT Music profiles.

What is Martin Cortis’s religion?

Martin’s religion is not publicly known. No official or fan sources have disclosed his religious beliefs, and it’s not mentioned in any profile. This is typical for K-pop idols, as religious affiliation is often considered private.

Is Martin an Irish name?

The name Martin has Latin origins, derived from Martinus, meaning “of Mars” or “warlike.” While it’s common in Ireland and other English-speaking countries, it’s not exclusively Irish. The name is used across many cultures, including French, German, Spanish, and Scandinavian contexts. Martin’s name doesn’t indicate any specific national or ethnic background.
