Please visit Harlow's Monkey for an interesting read on "The Family Tree", an adoptee's perspective.
"However there are spiritual blanks where the Kim family’s names should be. I see the personal history and family I don’t know as the shadow of my family tree – not the big leafy one represented by my adoptive family and their history, but as the strong silent presence fluttering behind it. My adoptive family is the one who guided and raised me, shaping my character; but my biological family is my instinct.
