This is the tombstone of Louis C. Fisher, located in row 12 of Kessler Cemetery (aka Liberty Cemetery), Mercer County, Ohio. The marker is inscribed:
J.C. & M.A. Fischer
Den 5 Jul 1876
2 Jahr, 5 Mo, 28 Tag
Louis C. Fisher, son of J.C. & M.A. Fischer died 5 July 1876, age 2 years, 5 months, 28 days.
Although this surname is spelled Fischer on the tombstone, the Fishers around Chatt, including the others in this family, spelled their name as Fisher.
Louis Charles Fisher was born in Liberty Township, Mercer County, Ohio, on 7 February 1874, the son of John Christian and Mary Ann (Bollenbacher) Fisher. His mother’s maiden name was recorded as Bollenbaugh on his birth record. 
Louis lived and died between census enumerations so very little is known about him.
Louis C. Fisher died of scarlet fever in Liberty Township on 5 July 1876. His death record gives his age as 2 years and 5 months, which differs slightly from his tombstone inscription. 
In fact, his birth date, as calculated from his age at death as inscribed on his tombstone, does not agree with his date of birth on his county birth record. I feel the county birth record is probably the more accurate record.
His sister Carolina E. Fisher (1872-1873) is buried next to him and his parents are buried a few rows away in Kessler Cemetery.
