난씨~

do you have a chinese name? if you have one then you can directly translate it into korean based on hanja pronunciation of chinese characters. chinese usually do in such way. sometimes it will come out with really nice or traditional korean names but of course not all the time. you can try to adjust or change it if it doesnt look nice.

korean girls have a few common names. so the names are not unique. I think you should have a new one regardless your name. I recommend '수민(sumin)' for you
