The Einhaus Family Tree, trees.ancestry.com/tree/23654037/person/1242552851 contains the Bailey family. It shows that William Anderson Bailey died 8 Aug 1921 in Saddle, Fulton, Arkansas. I wasn't able to verify this information.
Your best bet might be to pursue William's obituary.
William did have a brother Richard Morgan Bailey b. 1883 Phelps Co., MO who died in 1914 in Joplin, Newton, MO. Is this the Richard Bailey that you're seeking?
