I didn't find Levy nor Rachel's death records in Ancestry and FamilySearch. I might have found Levy on the Illinois Pre-1916 Deaths.
Levi Mcdaniel, died 1904-04-22, Orange, Clark, IL, age 68
I didn't find Rachel there.
Sometimes where a person was buried will be in their obituary and generally on their death certificate.
You can contact the Clark County Genealogical Library, www.facebook.com/
and ask about a copy of his obit/death notice.
You can contact the Bureau County Historical Society Museum & Library, http://bureaucountyhistoricalsociety.com/research.html
and ask if they have a local death index, indexed newspapers death notices or cemetery inventories.
I don't think they had death certificates. Successful Searching!
