Between all the members of SEVENTEEN, there are 11 known siblings in total! Most of the members have one sibling, while one has two siblings and three of them are actually only children. Some of them are also fairly private, while others have more known about them from what their idol siblings have said! Here’s what we know about the brothers and sisters of SEVENTEEN’s members.
Even though he’s the leader of SEVENTEEN, S.Coups is actually the only member of the group that has an older brother! His name is Seungmin (similar to S.Coup’s birth name, Seungcheol), and he was born in 1993, making him 2 years older than the idol. Besides this, not much is known about him!
Jeonghan is one of a couple members of SEVENTEEN that has a younger sister. She was born in 1999, making her 4 years younger than Jeonghan, and though her name isn’t known, he has hilariously said before that he wouldn’t let any members of SEVENTEEN date her! She also seems to be very crafty and creative.

Recently though, Hoshi shared on Pinggyego that he fights a lot with his sister since they are so close in age, but they also talk a lot since they can’t meet up in person often.
We would fight over the TV remote control or when I was playing a computer game, she would tell me to move aside. She would just kick me…
Yoo Jae Suk and Hoshi also discussed on the show how Hoshi’s sister is now working at a company.
Wonwoo is another member of SEVENTEEN that has a younger brother. His name is Bohyuk, born in 1998 (making him two years younger than Wonwoo), and he is actually a former fashion model! This isn’t too surprising, since Wonwoo has gorgeous visuals, and it must run in the family!
Bohyuk does have an Instagram account where he occasionally shares tidbits and insights into his personal life.
Woozi is the second member of SEVENTEEN that doesn’t have any siblings!
DK has an older sister in his family! Born in 1994, she is 3 years older than the idol, and she got married with the members of SEVENTEEN attending her wedding. Her name is unknown, but the two of them seem to have a cute and playful relationship!
seokmin had to get a reply from his sister in under 60 seconds so he told her he came second in the lottery and she replied in 25 seconds then called him#DOKYEOM #DK #도겸 #세븐틴 @pledis_17 pic.twitter.com/128m22HlxM

His oldest sister, Jinseol, is also active on Instagram, and based on her posts, the siblings all seem very close!
Vernon is the final member of the group that has a younger sister, who is arguably one of the most well-known SEVENTEEN siblings! Her name is Sofia (Korean name Hangyeol), and she was born in 2004, making her 6 years younger than Vernon.
Yet again, it seems that visuals run in their family, because she is undeniably gorgeous!
