This is the tombstone of Barbara Pfeifer, located in row 7 of Zion Lutheran Cemetery, Chattanooga, Mercer County, Ohio. The marker is inscribed:
Barbara Kuehm was born in Schillersdorf, Alsace-Lorraine, on 27 February 1870, the daughter of Michael and Elizabeth (Miller) Kuehm, sometimes spelled Kuhm. Barbara’s parents were also born in Alsace-Lorraine   and the family immigrated about 1873.  The Kuehms attended church at Zion Chatt and Barbara was confirmed there on 6 April 1884. Barbara was the sixth of seven known children born to Michael and Elizabeth.
In 1880 Barbara lived with her parents and 5 siblings in Jefferson Township, Adams County, Indiana, where her father Michael farmed. In their household: Michael and Elisabeth, both 53 years old; Michael (Jr), 19; Jacob, 17; Mary, 15; Lena, 12; Barbara, 10; and George, 8. All were born in Alsace. 
Barbara Kuehm married George Pfeifer on 25 May 1899, married by Lutheran pastor A.F. Klopfer. They were not married at Zion Chatt and, although they obtained their marriage license in Adams County, Indiana, their marriage record indicates they were married in Erastus, Mercer County, Ohio. George Pfeifer was 31 years of age, born in Ohio, the son of Christopher and Fredericke (Kniesel) Pfeifer. He was a farmer and resided in Knox County, Indiana, at the time of their marriage. Barbara was 30 years of age, born in Germany, and resided in Chattanooga, Ohio. Their marriage record indicates that she was the daughter of Michael and Elizabeth (Miller) Kuehm. Her nationality was listed as “for”, which I assume means foreign. This was the first marriage for both of them and Nicholas Pfeifer and Elizabeth Schott were witnesses to their marriage.  
I have not been able to locate Barbara and George in the 1900 census.
Barbara’s father Michael Kuehm died in 1909 and in 1910 Barbara and two children lived with her widowed mother Elisabeth Kuehm. Their household in 1910: Elizabeth, 83, head; Barbara “Phizer”, 40 daughter; Hilda [Pfeifer], 8, granddaughter; and Carl [Pfeifer], 6, grandson. The census indicates that Barbara was married but her husband George was not enumerated with them.  Barbara’s mother Elizabeth (Miller) Kuehm died two years later, in 1912. Barbara’s parents Michael and Elizabeth Kuehm are also buried in Zion Chatt’s cemetery.
Barbara and George Pfeifer moved to Van Wert, Ohio, about 1915, where they lived on Cherry Street. In 1920 they lived at 412 Cherry Street and their household consisted of: George, 50; Barbara, 49; children Hilda, 17, and Carl, 16; and Barbara’s widowed sister Katharine [Kuehm] Hoehamer, 62. George Pfeifer worked at a common laborer. This record indicates that Barbara immigrated in 1873. 
Barbara (Kuehm) Pfeifer died of cardiovascular renal disease on 25 June 1928 in Van Wert at the age of 58 years, 2 months, and 28 days, after suffering with the illness for three years. Barbara was a housewife and had resided in Van Wert for 13 years. Her address was 414 N. Cherry Street. Her husband George was the informant for the information on her death certificate. Barbara was buried on 27th.  Barbara’s death information was not recorded in Zion Chatt’s records.
Barbara’s husband George Peifer died in 1945 and is buried a couple rows from Barbara.
Barbara and George had two children and they were both baptized at Zion Chatt:
Hilda Margaretha Magdalena Pfeiffer (1902-1967), married Kenneth Guinn
Karl Heinrich Michael Pfeiffer (1903-1954), probably never married and was a WWII veteran
