I am looking for information on my great great grandfather Andreas Burkhardt. He was born in Wurtemberg in 1835. He immigrated to USA sometime before 1863. He lived in Williamstown Wisconsin for a time. He served in the Wisconsin 1st cavalry during the Civil War. He married a woman named Fredericka, also from Wurtemberg and their son Julius was born in Iowa in 1869. I am curious about Andreas parents and siblings, if he had siblings. There were a number of Burkhardts living in Dodge County Wisconsin around the same time and I'm wondering if they are related to Andreas. Their names are Christopher, Emil, George, Gustav, Phelix and Phillip. If anyone has any information please contact me.
