Thanks for the suggestions. You have educated me on what information is available in Washington state and who to contact for the details I'm missing.

Ancestry.com has a death REGISTRY, which is what I found without a place of burial. Hopefully, if I can order a death CERTIFICATE, it will provide his place of burial.

I appreciate your help with this search, which has a few problems, since Albert M Hawley may have been estranged from his family, and the circumstances of his death were not discussed in his family.
