http://www.floridamemory.com/Collections/PensionFiles/ Jerry and Alice are buried in Airline Baptist Church Cemetery, Mayo, Lafayette, FL, along with their son, William Codie (Cody)'s first wife, Nomie May Pearson (d/o Norman and Mala Jackson Pearson--Nomie's dates are 10 Mar 1906 - 18 Jul 1935, and she also died in Polk County, FL). Nomie was a very distant cousin of my father's; I'm sorry I don't have more information to share with you.
I hope this will break through your brick wall!
