A Smith family lived in Willshire Township in 1850, residing near Schumm, with Jacob Dietrich and Michael Schuler as neighbors. This Smith family included a Charles Smith, age 25. Karl went by the name of Charles Smith in 1851 when he married Rebecca Shell. This may or may not be today’s Karl C Schmidt, who may have gone by Charles Smith in this 1850 household: Charles Smith, 60; Regina, 51; Charles, 25; and Peter, 18. The three older members of the household were born in Germany, but the youngest, Peter Smith, was born in Ohio. 
Karl Schmidt, recorded as Charles Smith, married Rebecca Shell on 6 November 1851 in Van Wert County, Ohio. 
The Karl Schmidt family in 1860, living in Willshire Township: Karl, 34; Rebecca, 26; William, 6; Virginia, 3; and Charles F, 9 months. This enumeration indicates that Karl was born in Baden and the rest of the household was born in Ohio. Karl was a farmer.  At least one of their children, son William Henry Schmidt (1854-1926), lived to adulthood.
The Schmidts attended church at Zion Schumm in the early 1860s, where a son, Carl Samuel Schmidt, born 22 July 1861, was baptized at home on 29 July 1861. His sponsors were Carl Germann and his wife Elisabeth.
Within a year, both Rebecca and their son Carl had died, passing away within a day of each other.

His grave registration card indicates he was born 14 September 1824, but no birthplace was given.
