John Garmhausen was born in Osenburg, Germany, April 29th, 1832. He is a son of Bernhardt and Anna (Heinfeldt) 'Garmhausen. In 1836, Bernhardt Garmhausen and family left Osenburg for the United Stales. They had a tempestuous voyage and landed at Baltimore in the fall of that year. After remaining a short time at Baltimore, the family moved to Cincinnati. Here, John Garmhausen grew to manhood. The discovery of gold in California in 1849 produced great excitement in the middle and eastern states. In 1850 young Garmhausen joined a party of gold seekers at Cincinnati and made the trip overland to the new El Dorado. He labored in the mines near Sacramento City until 1852, when he returned to Cincinnati. In the same year he located near New Bremen. For fifty-three years he has been a participant in the development of German township and adjacent country. Soon after locating at Lock Two he engaged in mercantile pursuits. He also built a large flouring mill and warehouse, and a few years afterward erected a saw mill. In 1854, he married Miss Mary Strasburg. Of this union nine children have been born: Florenz, Edward, Charles, Benjamin,
