Trying to find information on Lars Oscar Anderson

I am trying to find information on Lars Oscar Anderson. His parents were Ole M Anderson and Martha (Johnson) Anderson. He was born: Dec. 8, 1886 but I don't know when he died. He was ordained in the Lutheran Free Church in 1910. I'm not sure if he was married. I would like to find out when he died and even more about his siblings. I know he had siblings named Sophia (Sophie), Arthur, Matilda, Mabel, and Ruth. Sophie married Carl W. Quankbeck, but I don't know anything else about the other siblings. Any help would be appreciated!
