I am searching for my half sisters who are half Japanese. They are the daughters of an American man, Richard T. Bivens and a Japanese woman, Naomi (unsure of her last name). The two sisters were adopted by their step-father when their dad, Richard, remarried and moved to the US. Their names should be Angela and Michelle. I believe that the older one would be around 30 years old and the younger one in late twenties possibly. I have never met them and I wish to find them. I am their younger sister (22 years) and they have one brother too, Steve (almost 21 years) who wishes to know his sisters. If any one has any suggestions please help me. I am far away from Japan in America and wish to some how locate my sisters, Angela and MIchelle!!
