I have found August, Peter, Heinrich, and William Berger in the Gasconade County, Missouri census'.I am tracing Peter Heinrich Berger who immigrated with his family from Herford, Westfalen to New Orleans in 1854.
Henry Berger was born about 1813(by the 1860 census dates). I believe Peter and Heinrich are brothers but haven't found anything to prove that either way.
I have found a Anne Catherine Ilsabein Berger in the Gasconade County Cemetary index. I would have to dig out my information to get anything specific on her.I would be willing to share/trade any information I have on this family
