Is this the John Greenlees you are looking for? My files have a John Greenlees born 14 Jun 1846 in Ohio, died 5 Jan 1894, buried Deersville Cemetery, Deersville, Harrison County, Ohio, married 27 Mar 1873 in Harrison County, Ohio to Mary Jane Czatt daughter of John Czatt and Sarah Jane Johnson Czatt. I have a note that says in the 1860 Census Monroe Township, Harrison County, Ohio on page 229 that John Greenlees is listed as 14 years of age. Hope this was of some help.
