Johann Ludwig “Louis” Allmandinger was born 26 November 1829 in Aldorf, Württemberg. He was later known as Louis Allmandinger Sr and his son as Louis Jr.
Louis Allmandinger married Rosina Schneider on 4 March 1857 in Butler County, Ohio.  Schneider was later sometimes spelled Snider or Snyder.
Rosina “Rosa” Schneider was born 4 October 1833 in Württemberg.
In 1870 the family lived in Butler County, Ohio, where Lewis, age 40 farmed. In the household were Rosa, 35, Lewis, 12, Michael, 11, John, 8, Jacob, 5, William, 3, and Fredric, 8 months. This record indicates that Lewis and Rosa were born in Württemberg and the others were born in Ohio. 
They resided in Butler County for several years and most of their children were born there. The family moved to Blackcreek Township in Mercer County sometime between 1870 and 1880. Their farm was a little over a mile north of Chatt, along State Route 49, then known as Brandt Pike.
In 1880 their family consisted of Lewis, 51; Rosina, 46; Lewis, 23 (no relationship given); children Michael, 22; John, 17; Jacob, 15; William, 12; Frederick, 10; Mary, 8; Lena, 6. Lewis Sr and their sons worked on the farm and all except Lewis and Rosina were born in Ohio. This census indicates Lewis and Rosa were born in Württemberg. 
Louis died 8 April 1888 at the age of 58 years, 4 months, and 9 days and was buried on the 10th.
In 1900 Rosina, 66, born October 1833, was a widow living by herself in Blackcreek Township. She owned her own home free and clear. She had given birth to 10 children but only 7 were living. She was born in Germany but her date of immigration was not given. She was living next door to her son William C, 32, and his family: wife Barbara S, 22, and sons Richard E, 1, and Walter L, 3 months. William was born in Ohio in Sep 1867. 
In 1910 Rosina, 76, still lived by herself on Brandt Pike in Blackcreek Township. One of her children had died since the last census enumeration, leaving six of her ten children living. She could read and write and speak English and she owned her own home. This enumeration indicates that she immigrated in 1849.  Some accounts indicate they immigrated in 1857.
Rosina Schneider Allmandinger died 12 January 1915 at the age of 81 years, 3 months, and 8 days. She was buried on the 15th. Survivors included 4 sons, 2 daughters, 38 grandchildren, and 1 great-grandchild. Rev. Gahre was in charge of the service.
