Hi, Karen: I recently came across your gracious posting which acknowledged your adoption as well as your name at birth: Sharon Marie Icenogle. I do not know to whom you were born, but I've made a lifelong study of the name Icenogle and have a lot of data on those who lived in Michigan. If you have ANY more information about your birth parents and/or would like to investigate possibilities, I'd be glad to share what I have. Best wishes.
Roger Icenogle
