Different last names

In Korea women's last names stay the same after they're married, unlike western cultures.
Children take their father's last name, but that doesn't mean their mother have the same surnames as them. These days some feminists want thier children take their last names, and some people insist on using both father's and mother's last names, like Kim-Park.

This is my family tree.

c.f. Korean Last names
The most common last name is Kim 김. 21. 6% of Korean people are Kims, according to the survay in 2000. Then comes Lee, Park, Choi, Jeong, Kang, Cho, Yun, Jang, Yim.
Some of the "unique" names are Kang Jeon강전, Kae개, Kyo교, Kun군, NAn난, Nae, Noi뇌, Nu누, Dan단, Dam, Don돈, Mangjeol망절, Myo묘, Bi비, Sam삼, Sobong소봉, Su수, Sun순, Sib십, Eogeum어금, Yeong영, un운, Jang'gok장곡, Jeo저, Jun준, Cho초, Chun춘, Hu.

My last name, Jeon(전), isn't really common one I heard.
But I like it cause my friends in America could say it easily.

Same for my first name, Suli. This is a REALLY unique name in here.

(it almost sounds like American name they say. I've saw person in my name

just once in my life so far.)

It is traditional to name children with chinese characters(hanja), for example my name composes of two different chinese letters, Sul(to speak and write) and I(it's actually conjuncture, really don't have any meaning). Of course the last names are all chinese characters. One more thing, people with same last names might come from different origin.

Sul (述)+ I(而) -> Suli

Jeon (全,complete)
