Carl and Josie (Erickson) Hansen

I am trying to find my great uncle and his family. Carl Hansen (born without a middle name, so he picked W. for work) was born 18 November, 1885 in Missouri Valley, Iowa. He died 12 Dec 1961 in Portland. He married Josephine Erickson and lived in Portland, Oregon. He had two boys, I believe, Donald and Philip?. One of the boys had several children by the names of Carlyle Hansen and Linda Hansen whom I am told was married to a Joe Malia, thus making her Linda Malia. Am trying to hunt down this relation. Any help is appreciated.
