Although these are not records, and you may have already seen them, I thought I would provide this:
Ancestry - Stories, Memories, and History>"C">"Cu">"Cum", enter >"History of Jasper, Cemberland and Richland Counties" - search for "Decius."
On IL Genealogy Trails>Cumberland Co, searh Toledo bios, Early Settlers, Origin of Cumberland Co., and Early County.
I wish you good luck.
