Descendants of Leo William Utter not related to Nicholas M. Utter

My father, August Matinpoika Utter was born in Oravasaari, Finland on September 19, 1887. He came to the United States in 1909, originally to Grayling, Michigan, with his brother, Matti Utter, and lived most of his life in Seattle, Washington, where he died April 1, 1960. He married Jenny Lehto, also a native of Finland, and two sons, my brother Hugo August Utter and myself, Leo William Utter, are the result of that marriage. I am single, but my brother has two sons in California. My uncle Matti Utter lived mostly in the Ontonagon, Michigan area on the Upper Peninsula, had two daughters and a son.
