I'm searching for my great-great grandfather Peter Nau whose sons immigrated to the U.
S. Baltimore-Washington, D.C. area, just after the Civil War in the 1860's.. There were three of them (Heinrich, Ignatius, and Adam. Peter never immigrated but lived in the city of Kassel. Ignatius was my great-grandfather and was married to my grandmother Maria Kathrina Fladd. They were married in Washington, D.C. in 1872. They had nine children. Why did these brother immigrate? They may have been avoiding the service in the army. Please let me know if anyone has any information of my relatives. I do not know who Peter was married to.
