I have been searching for family members. I was put up for adoption with my brother in 1952. Last name of birth mother at the time was Marie Olsen or juliana marie olsen. My mother was born in 1911. She was born in Norway. She got married and had another baby about a year later. She had a brother who was in the service and a sister. They all lived in New Jersey at the time. My brother was born two years before me. We are blood brother and sister and I am trying to find family members that might have a picture of my mother who possibly know what happened to her.
You might try searching "Genforum Olsen" in a search engine such as google. It will take you to the Genforum website. Then put in a search and/or query for New Jersey and Norway. You might be lucky. Good luck.
if the brother was in ww2 he may have gotten post war benefits and listed next of kin..his sister or you mom. search mormon indexes too...very comprehesive. Put your name on their index tofind out more.
