The above provides his exact death date but doesn't really say where he died. I see you posted in San Joaquin Co. so I'm going to assume he died there.

You might have quicker luck if you do a Google search for Grays Harbor Public Library.
I also found a Lee-Wiley Family Tree, trees.ancestry.com/tree/3651952/person/619338979 . They show a George M. Hughes, b. 20 Aug 1928 who died 2000, Aberdeen, Grays Harbor Co., WA.
His wife was Patsy A., b. 7 July 1937 who died 7 Dec 1993 in Olympia, Thurston Co., WA.
They had three children but no info available because they're still living.
Unfortunately I didn't find anything for Richard. Successful Searching!
