Robb, did you ever get the information you were seeking on this post? My information is fragmented right now, as I'm just finding connections to the Amazonia Zimmermans who came from Ragersville, OH to my Zimmerman family. The Susanna of my info so far, married a John Megert, probably not your Susanna. Her father was Danial Zimmerman from Wattenwil. He immigrated to Ragersville, OH, in 1835. He had three children, Anna, Dan, and Susanna. His wife died and was buried in Switzerland along with another son. Have you tried the Ragersville, OH. Historical Society??
