From an Emigration Index put out by the Pirmasens Genealogical Study Group, we learn that Ludwig Neuert (born 1809) and his wife, the former Elizabetha/Elizabeth Hohl, and their sons Johann Michael Neuert (born in 1834, later known as John) and Johann Jakob Neuert (born in 1837, later known as Jacob) all were from Leimen, Germany, and emigrated to the United States to settle in Sandusky, Ohio in the year 1846.
Ludwig Neuert became known as Louis Neuert. He and his wife made their home in Sandusky with their son Jacob. Ludwig/Louis Neuert worked in a grocery store. In time, Jacob Neuert would become the superintendent of the Barney and Kilby Machine Works, and would be issued several patents for his patterns and inventions. Jacob moved his family to Chicago in the late 1890's. John Neuert worked as a boilermaker. He and his wife had several children listed in the 1880 U.S. Census.
Ludwig Neuert died at age 75 on October 12, 1883. He is buried in Sandusky's Oakland Cemetery. His wife Elizabeth Neuert had preceded him in death in 1873.
