Here are the obit index entries for Loose from the Dayton library...Note that 1900 thru 1984 haven't been indexed for the most part, so only Donald F. on your list shows up here.That doesn't mean that obits aren't available, they just haven't been indexed yet.
I'll try and take a quick look Saturday if I'm not out of town and see what I can find.
