There certainly are a lot of McFadden's buried in Wayne Co.The closest to your information I found is as follows:
CHESTER TWP Mohican Cemetery McFADDEN Mary w/o W. McFadden age 48y ?m 6d (could not read more) Daniel died Aug 2, 1891 age 86yrs Joseph S. son of D & R died May 8 1867 age 22y 5m 11d Capt. James (Flag) Co. H 63rd OVI killed at the battle of Corinth Miss. 10/4/1862 age 27y 6m 14d John W. died 8/11/1870 age 40y 6m 26d Rachel d. 9/12/1891 86y Robert T. 6/1847-4/6/1907 Mary (his wife) 10/6/1844-6/22/1911
If you come across census information that places them in a particular county late in their lives that was then or is now Wayne Co., please let me know and I will be happy to re-do the lookup for that twp.This was the only Daniel, by the way.The stone could have been misread as well.One final note, Chester Twp borders Ashland Co.
