I was wondering if this family was familiar to anyone?

Henry Kanna b Hanover ~ 1807
Hanna ? Kanna b Baden ~ 1822
both likely died before 1880

Children:

Peter b Illinois ~ 1847; Henry b Illinois 13 Oct 1850; Charles b Illinois ~ 1852

Between 1860 and 1870 the family lived in Clinton and Bond counties in Illinois

By 1880 the 3 children's last name was spelled Kaune. In the 1880 census Peter and Henry were living in Bates County Missouri, and Charles in Bond County Illinois.
