This is the tombstone of Oscar F. Heffner, located in row 9 of Zion Lutheran Cemetery, Chattanooga, Mercer County, Ohio. The marker is inscribed:
Oscar Heffner was born in Chattanooga, Ohio, on 27 June 1896 to Fredrick and Anna (Merkle) Heffner. He was baptized as Friedrich Oskar Heffner at Zion Chatt by Rev. P.J. Vollmar on 12 July 1896. His parents served as his baptismal sponsors. Oscar was confirmed at Zion Chatt on 9 April 1911 by Rev. George Haas.
Oscar registered for the WWI draft in Celina, Ohio, on 5 June 1918. He was living at RR 5 Rockford at that time and working for E.J. Drake in Mendon, Ohio. He had gray eyes and brown hair.  Oscar enlisted 5 September 1918 and served as a private in Co K 29 Engineers until his honorable discharge on 27 December 1918. 
Shortly after the war Oscar lived in a boarding house in Mendon and worked as a mechanic in a garage.  At some point during his life Oscar acquired the nickname Brownie.
Oscar Heffner married Lillian Kinkley at Zion Chatt on 29 October 1921 by Rev. Carl. H. Albrecht, who also served at their witness. Zion’s records indicate that Oscar was 25 years old and Lillian was 20 years old. She was born on 17 December 1901 in Mendon, Ohio, the daughter of Robert and Edith (Hall) Kinkley. At the time of their marriage Oscar was a mechanic and Lillian was a telephone operator. 
In 1930 Oscar lived on Main Street, Mendon, where he was the proprietor of a garage. Oscar indicated he was the head of the household and his brother Vernon lived with him. Oscar was 33 years of age and married while Vernon was 24 and single. Vernon was employed as a mechanic in the garage. Only Oscar and Vernon were enumerated in the household. Lillian was living with her parents, Robert and Edith Kinkley, on Wayne Street in Mendon. 
Oscar and Lillian divorced in 1937  and Oscar still resided with his brother Vernon in 1940. Vernon, now the head of the household, was married to Carmella. The two Heffner brothers worked as mechanics in their garage. 
Oscar registered for the WWII draft, the “the old man’s registration,” in 1942. He was 45 years old at the time, self-employed, and living in Mendon. 
A few years later Oscar married a second time, marrying Dorothy Evelyn Patton on 9 December 1946 in Jay County, Indiana. The marriage was performed by Rev. Marshall N. Weaver. Dorothy was born 20 August 1918 in Ashville, North Carolina, the daughter of W. H. and Verna (Ball) Patton. She had also been married once before and had divorced in 1940. At the time of their marriage Oscar lived in Fort Wayne, Indiana, where he operated a service station. Dorothy lived in Decatur, Indiana, and was not employed. 
According to Zion Chatt’s records Oscar had made his home with his brother Vernon in Mendon for 39 years when he died of heart trouble at 9:45 p.m. on the evening of 27 September 1956 in a Celina hospital. Oscar was 60 years old and was buried on the 27th. Oscar’s obituary:
Oscar F. Heffner
Mendon—Services will be at 2 p.m. Thursday in the Zion Lutheran Church, Chattanooga, for Oscar F. Heffner, 60, of here, who died Monday evening in the Gibbons Hospital, Celina, following a heart condition.
A lifelong resident of Mercer County, Mr. Heffner was a retired owner and operator of a service station and garage business here, in which, his brother, Vernon, was a partner. He was a veteran of World War I.
He is survived, in addition to his brother, Vernon, with whom he had made his home, by another brother, Rudolph, Chattanooga, and a sister, Mrs. Marguerite Roebuck, Fort Wayne.
The body will remain in the Vernon Heffner residence where friends may call until time of services. Burial will be in the church cemetery. 
No children were mentioned in any of the records.
Oscar and his second wife Dorothy must have divorced sometime before 1960 and it appears she took her maiden name back. Dorothy E. Patton married Lee F. Daniels on 9 March 1960 in San Luis Obispo, California.  Dorothy Evelyn Daniels died on 21 August 1996 in San Luis Obispo.
