McKinney, William McClure - Fountain Photos

Son of Presley Thompson and Sarah Jane McClure McKinney. This is the great granduncle of Jeff Quirk, who graciously let me use this photo. William was in Co I, 15th Indiana Infantry, mustering in as 2nd Lt. on 24 April 1861 (from Covington, Indiana) promotoed to 1st Lt. 10 Sept 1861 then Captain 9 Nov 1862. Mustered out 25 June 1864. His dairy is in Wabash College Archives. He seems to be buried in the (at Wingate but since in Fountain County must be near Wingate over the county line) Oak Ridge Cemetery but no death date - just 28 Years 5 Months 19 days - if he was mustered out because of death, then he would be born 6 December 1835 which tallies with the 1850 & 1860 census. Anyone know for sure, let me know :) THANKS
