Have you found any more leads on your Donald Snelling??I had sent you the SS index on a Donald Smalling from Washington but while working on the Snelling line I ran into several charts on a Donald Snelling & Roberta Leeds on the Rootsweb.com site (click on Trees)and they listed this family from King Co, WA. If you go to these sites, the submitters emails are listed.
Found this for the state of Washington, Deaths: I already sent you this one from the SS death index, Name: Donald K Smalling Place of Death: Yakima City Residence: Yakima City Gender: M Date of Death: 05 May 1972 Certificate: 012276
But this might be yours, notice he died in King County, WA.: Name: Donald R Snelling Place of Death: King Residence: Kent Gender: M Date of Death: 29 Apr 1967 Certificate: 010713 You could check the SS Death Index and order his paperwork.
