This is the tombstone of Philip and Etta (Leistner) Huffman, located in row 3 of Kessler Cemetery, Liberty Township, Mercer County, Ohio. The marker is inscribed:
Philip Huffman was born 24 December 1859 in Mercer County, Ohio, to Ferdinand and Elizabeth (Herzog/Hartzog) Huffman. He had a twin sister Elizabeth. Zion’s familienbuch indicates that the twins were baptized in Mercer County, Ohio, but their baptisms are not recorded in Zion Chatt’s records. Philip was confirmed at Zion Chatt on 14 April 1874 but there is no record that Elizabeth was confirmed there.
In 1860 the Huffmans lived south of Chatt and had a Skeels Cross Roads Post Office address. Philip was enumerated in the 1860 census when he was just 8 months old.  He was enumerated in the 1880 census with his parents and six siblings and his occupation was a carpenter. 
Philip and his twin sister Elizabeth, age 37, were both still living at home with their parents in Liberty Township in 1900. Both were single and Philip was a day laborer. 
Philip Hoffman married Etta Leistner 29 April 1903 at Zion Chatt, married by Zion’s minister R.V. Smith. Etta was 28 years old, born in Blackcreek Township, Mercer County, in August of 1874, the daughter of John and Leana (Hinton) Leistner. Etta used the name Ethel on her marriage license. Philip, age 39, lived in Chatt and worked as a carpenter. Neither was previously married. 
Etta’s date of birth was recorded in Blackcreek Township as 25 August 1874. 
Etta Leistner grew up in Blackcreek Township. She was baptized, christened as Leiniette, at Zion Chatt with her younger sister Flarensdelle on 26 June 1876. Their baptismal sponsors were Barbara Leistner and Catharina Beyer. Their mother’s name was recorded as Magdalena (Hinton) Leistner. Etta’s name is shown as Ettie in some records.
The extended Leistner family lived together in 1880: Andrew, 72; Barbara, 68, wife; John, 34, son; Andrew, 25, son; Leann A, 30, sister-in-law; Sinsetta, 5, daughter; Florance D, 4, daughter; and Barbara E, 2, daughter. The older couple, Andrew and Barbara, were Etta’s grandparents. The daughter enumerated as Sinsetta was Etta and she was disabled, with what was described as a spinal contraction.  Apparently Etta’s given name was Sinsetta or Leiniette or something similar. The handwritten S and L can be difficult to differentiate and is indexed differently on different records.
The Leistner household in 1900: John, 54; LaAnn, 52; Etta S, 25; Barbara E, 22; Anna E, 16; John H, 13; and Mary M, 11. John and Leana had been married 28 years and had had 8 children, but only 6 were living. John was a farmer. Etta was born in August 1874, was single, could read and write, and spoke English. This enumeration indicates that Etta’s middle initial was S. 
Etta married Philip Huffman in 1903.
The Philip Huffman household as enumerated in 1910: Philip, 52, Etta, 36, and their daughter Bernice, 3. Bernice was the only child they had. Philip was a general farmer and he and Etta had been married 7 years. 
In 1920 the Huffmans lived on a farm. In the household: Philip, 57; Etta, 46; their daughter, enumerated as Grace, 13; and nephew Jesse, 14. Philip still worked as a general farmer. 
Philip, 68, and Etta, 55, lived by themselves in 1930. Philip worked as a carpenter, doing public work. 
I have to wonder who reported their ages in these census enumerations. The ages certainly varied a lot!
In 1940 Philip, 81, was an old age pensioner, likely retired from farming completely. Etta, age 65, did not work. The highest grade Philip completed in school was the 6th grade and Etta had completed the 5th grade. They lived in the same house as they did in 1935. 
According to Zion Chatt’s death records Philip Huffman died of complications at 9:30 p.m. on 15 October 1954 in Celina, at the age of 94 years, 9 months, and 21 days. He was buried on the 18th. He was survived by his wife Etta; daughter Mrs. Grace Raudenbush; 2 grandchildren; 2 great-grandchildren; and a sister Mrs. Rose Zellinger. The record goes on to state that he was born 24 December 1859 to Ferdinand and Elizabeth Hartzog Huffman. He was one of a pair of twins who was baptized, and was confirmed on Jubilate Sunday in 1875 by Rev. Schmidt. He was married 29 April 1903 by Rev. R.V. Smith.

She was survived by her daughter Grace Raudenbush, 2 granddaughters, Mrs. William Nash, and Nila Sue Raudenbush; a brother John Leistner, 2 sisters, Mrs. Charles Kuhn, and Mrs. Martin Affolder.
