Hi Phil,
You'll have better success if you request a copy of his obituary.
A Harry E. Tilley b. 14 Sept. 1905 died 1 Sept. 1987, Yakima,
Yakima Co., WA. Source: Social Security Death Index,
www.ancestry.com.
There are a couple of volunteers for obits on Random Acts Genealogical
Kindness,
www.raogk.org. Read the instructions, choose
Washington, choose
Yakima Co.
You can also request an obituary published in WA from the
Washington State Library,
www.secstate.wa.gov/library/ask.aspx . They will search the newspaper microfilm for 60 minutes at no charge and email to you what they do or don't find.
After I receive the obit, I use
www.whitepages.com to find current contact info for survivors. Successful Searching!
