Karen Joyce Murphy, DOB March 4, 1942, Brookfield Missouri

My name before I was adopted was Karen Joyce Murphy and I was born on March 4, 1942 in Brookfield, Missouri. I am looking for any information about my life or my family. I was taken to an orphange in Davenport, IA and was adopted from there when I was 5 years old. Any information would be helpful. Thanks so much!
