This is the tombstone of Jacob and Margaret (Huffman) Bollenbacher, located in row 8, Kessler Cemetery, Mercer County, Ohio. The marker is inscribed:
Jacob Bollenbacher was born in Petersbach, Germany, on 28 October 1848, the son of Abraham Bollenbacher.  Some sources show that his mother’s name was Maria Katharine Kuhn. He immigrated to America in 1871. 
Jacob Bollenbacher married Margaretta “Margaret” Huffman 21 February 1878 in Mercer County, Ohio, married by Rev. CJ Bohnen. 
Margaret Huffman was born in Liberty Township, Mercer County, Ohio, on 3 January 1855, the daughter of Ferdinand & Elizabeth (Herzog/Hartzog) Huffman. The name was spelled Hoffmann in some of the old records. Her parents were born in Germany. Margaret was confirmed at Zion Chatt on 1 April 1871.
Margaret Huffman lived south of Chatt in 1860, where the family had a Skeels Cross Roads Post Office address. Their household in 1860: Ferdinand, 30; Elizabeth, 26; George, 7; Margaret, 4; John, 2; Elizabeth, 8 months; and Philip, 8 months. 
After their marriage Jacob and Margaret Bollenbacher lived across the state line in Adams County, Indiana, where Jacob farmed. In their household in 1880: Jacob, 31; Margaret, 24; and Augustus, 1. 
In 1900 Jacob and Margaret and their five children lived in Jefferson Township, Adams County, Indiana. In their household: Jacob, 51; Margaret, 44; August William, 21; Dora C, 18; Jesse Charles, 16; Abraham, 16; and Rosa C, 13. This enumeration indicates that Jacob immigrated in 1871. Margaret had given birth to 8 children but only 5 were living. All of their children were reportedly born in Indiana and Jacob farmed for a living. 
Their household in 1910, Adams County: Jacob, 61; Margaret, 54; Jess, 27; Rosa, 23; and Wilber Anspaugh, 7 [grandson]. Wilbur Anspaugh was their daughter Dora’s son. Dora died in 1902 and now only 4 of the 8 Bollenbacher children survived. It appears son Jess had taken over the farming. Jacob reportedly did odd job on the farm while Jess farmed.  They lived very close to my relative Winfield Brewster.
Jacob and Margaret still resided in Adams County in 1920, where Jacob again farmed. Still living with them was their grandson Wilbert T Anspaugh, 17. 
Margaret (Huffman) Bollenbacher died 7 July 1921 in Liberty Township, Mercer County, at the age of 66 years, 6 months, and 4 days. Her cause of death was rheumatic arthritis and nephritis with gastritis as a contributing factor, a condition which she had for 9 years. SS Egger was in charge of the funeral arrangements and she was buried on 9 July. 
Jacob Bollenbacher died of pneumonia on 15 May 1929 in Decatur, Adams County, Indiana, at the age of 80 years, 6 months, and 3 days. His occupation reportedly was retired farmer. Egger & Ketcham were in charge of the funeral arrangements and Jacob was buried on the 3rd. His son GW [August William] Bollenbacher was the informant for information on Jacob’s death certificate, information that indicated Jacob was the son of Abe Bollenbacher, mother’s name unknown, and was born in Petersbach. 
Jacob and Margaret (Huffman) Bollenbacher had at least 8 children, three of whom died in infancy before 1900. Those children may also be buried in Kessler Cemetery. There are two two infant sons, children of J & M Bollenbacher, who died in 1888 and 1893, buried side by side there. The 5 Bollenbacher children who reached adulthood:
