This is the tombstone of Louisa Marie Kable, located in row 6 of St. Paul UCC Cemetery, Liberty Township, Mercer County, Ohio. The marker is inscribed:
Louisa Marie Kable was born in Mercer County, Ohio, on 11 October 1866, the daughter of Ferdinand and Catherine (Bollenbacher) Kable. Both of her parents were German immigrants.
The Ferdinand Kable family in 1870: Ferdinand, 43; Catharine, 37; Adam, 9; Caroline, 7; Louisa, 3; Catharine, 1. 
The Ferdinand Kable family in 1880: Ferdinand, 54; Catharine, 45; Adam, 17; Caroline, 16; Louisa, 13; Catherine, 12; and Nettie, 8. Louisa attended school and her father Ferdinand was a farmer in 1880. 
The Ferdinand Kable household in 1900: Ferdinand, 72, head; Catharine, 67, wife; Louisa, 33, daughter, single; Kattie [Katharine] Dittinger [sic] [Dellinger], 32, daughter, widow; Emil Kable, 11, grandson; Henrietta Bollenbacher, 95, mother-in-law, widow. Louisa was not employed. 
The Ferdinand Kable family in 1910: Ferdinand, 82; Catharine, 77, wife; Louisa, 43, daughter, single; Catharine D, 42, daughter, single; Henry Leininger, 23, nephew, single. Louisa was not employed. 
Louisa Kable’s father Ferdinand, a Civil War veteran, died 14 January 1912.
In 1920 Louisa Kable, 53, single, lived with her widowed mother Catherine Kable, 87, and her younger sister Catherina, 51, divorced. The three women resided in Liberty Township and none were employed. 
Louisa’s mother Catherine (Bollenbacher) Kable died 25 June 1922.
After their mother’s death it appears that Louisa and her sister Katherina C. Kable moved to Pleasant Township, Van Wert County, and lived with their sister Henrietta and her husband Christian Merkle.
Louisa Kable died in Pleasant Township, Van Wert County, Ohio, on 10 February 1930 from complications of dementia. She probably died at the home of Christian and Henrietta (Kable) Merkle, her brother-in-law and sister. Louisa was 63 years, 3 months, and 29 days old and was buried on the 12th. 
Louisa did not live to be enumerated in the 1930 census. She never married. It appears Louisa was never employed outside the home but probably helped around the house and cared for her parents.
