Hi, I've found that finding obituaries helps you to find descendants. The survivors of the deceased are generally listed in the obits and then I use www.whitepages.com to find contact info for them.
I found Elzie and Aurora Riddle living in Indian Creek, Lincoln Co., WA in 1920. Elzie E., b. NC, 47 yrs old, general farmer; Aurora B., b. NC, 40; Phillip C., b. NC, 19, single, laborer general farm; Texie A., dau, b. NC, 17; Virgil E., b. WA, 14; Glen E, b. WA, 18; Gordon G., b. WA, 7 and Alton B., son, b. WA, 3 3/12ths.
An Elzie E. Riddle died 8 Aug 1950, age 77, b. abt. 1873 per death cert #14629. Source: WA Death Index 1940-1996. Elzie's obit might be difficult to locate since the index doesn't say where he died.
You can contact the Washington State Library, www.secstate.wa.gov/library/ask.aspx for any obit in Washington state. They will search the newspaper microfilm for 60 minutes at no charge & reply with what they find.
There is also a volunteer for Lincoln County on Random Acts Genealogical Kindness, www.raogk.org, choose Washington, choose Lincoln Co who does Public Record lookups and copying. I'm not sure if that includes obits.
