My 2nd Great Grandfather was Wiley J. Martin from DeKalb County, Tennessee. He was a Union Civil War scout with Co F, 4th Tennessee Mounted Infantry from September 24, 1864, to August 25, 1865. His records indicate he was blinded during the winder of 1864/65. According to pention records, he died June 18, 1908, possibly in Mechanicsville, Rutherford County, Tennessee. Can anybody help me locate his grave?

Thank you!
