Hi Harold, have you contacted John at Random Acts Genealogical Kindness, www.raogk.org, choose Washington, choose Island County? He does public record lookups and might be able to find Delbert's birth cert which will list his parents. Any chance an obit was published for Delbert? John does obit looks ups for Oak Harbor/North Whidbey County too. Successful Searching especially for such a worthy cause!
