This is the tombstone of Michael J. and Margaret “Maggie” Kallenberger, located in row 10 of Zion Lutheran Cemetery, Chattanooga, Liberty Township, Mercer County, Ohio. The marker is inscribed:
Michael J. 1871-1952
Johann Michael Kallenberger was born in Blackcreek Township, Mercer County, Ohio, on 16 March 1871, the son of Andrew and Elisabeth (Burkhart) Kallenberger. He was baptized 14 May 1871 and confirmed 17 May 1885 at Zion Lutheran Church, Chattanooga.
Maggie Rueck was born 26 March 1879, according to her confirmation record at Zion. She was confirmed 9 April 1893. Maggie was born in Germany [probably Württemberg] to Christine Rueck. Maggie, her mother and her mother’s family immigrated to America about 1879,  but I have not located them on a passenger list. Maggie was my grandaunt and it appears that she was adopted by Jacob Miller after he and Christine Rueck married.
Mike and Maggie were married on 30 September 1897 at Zion. They lived on the Kallenberger farm, Section 17 of Blackcreek Township, Rockford West Road, until Mike died. After that Maggie turned the farm over to their son John and Maggie moved across from the Vernon Caffee farm on State Route 49, about 1 1/2 miles north of Chatt.
Relatives that remember Maggie have told me that Mike and Maggie were considered fairly well-off. They owned a refrigerator that was run by kerosene and they had a Delco System that worked like a generator and supplied their electricity. My Aunt Ruth remembers that Maggie popped a lot of popcorn.
Mike and Maggie adopted two children, George Wesley, born May 1906, baptized 30 May 1909 at Zion, Chatt, and Ardella, born 7 January 1908, baptized 30 May 1909 at Zion. One child was born to them, Johann Andres Kallenberger, born 5 October 1910, baptized 6 November 1910.
Mike and Maggie also raised Bob and Merlin Miller, sons of her half brother John Miller and his wife Frona (Dull). And they raised their grandson Max Kallenberger, Wesley’s son, after his mother died and Wesley was drafted into the Army during WWII, leaving no one to care for the young children.
Mike and Maggie were baptismal sponsors for Vernon Caffee in 1915 and Maggie was the sponsor for several other nieces and nephews.
