When a woman gets married in Korea she does not change her name. When she has children, they will have the name of their father. Most given names in Korean are 2 syllables. It is very common for siblings to share a syllable, just like 승조 and 은조.

Korean name is composed of Family name and Given name. Traditionally, Korean women keep their family names after their marriage, but their children take the father's surname. In the premodern, patriarchal Korean society, people were extremely conscious of familial values and their own family identities. Korean women keep their surnames after marriage based on traditional reasoning that it is what they inherited from their parents and ancestors, and cannot be changed. Traditionally, given names are partly determined by generation names, a custom originating in China. One of the two characters in a given name is unique to the individual, while the other is shared by all people in a family generation. In both North and South Korea, generational names are no longer shared by cousins, but are still commonly shared by brothers and sisters. For example, in 백승조 and 백은조, 백 is a family name. 승조 and 은조 is a given name. 조 is a generation name (in Korean, 돌림자 or 항렬자) For more information, refer to http://en.wikipedia.org/wiki/Korean_name http://en.wikipedia.org/wiki/Generation_name
