A work buddy told me about a cool website, findagrave.com, where you can look for gravesites in a variety of ways. You can search on a name or search at a specific cemetery.
I tried Fairmount Memorial Park on Spokane's North side. And though it lists, in alphabetical order, about 6.000 people buried there, the searches on my family members buried there didn't find them but I did find some old friends of my parent's.
Anyway, it's worth a look.
