Selmar Langager

First let me say Thank You to everyone who has helped me in my research. I greatly appreciate all your help. My sister, Naomi, years back had visited with our cousin Audrey Lee Nelson (Marjorie and Morris Nelson's daughter) She said Audrey had been to Norway and found a cousin. His name was Selmar Langager. I was wondering if anyone could help me find information about him. Other than his name I have no information about him. Any help will be appreciated. Thank you
