Huge German influence in Iowa after the civil war. Really picked up in the 1870s from what I can tell. And I do know my own lineage were one of those families. My great great grandpa spoke German until he died in 1937. He migrated here in the early 1870s from my research. The property and home he built is still lived in by my cousins. I also have German ancestors from Maryland sometime in the revolutionary war time period, and that family (whose name I still carry) moved west slowly over a century to get to Iowa, stopping in Pennsylvania and Ohio along the way for a few generations. Where I live though, the English and French were primary settlers around here. Wow, I can’t wait to hunt. Dang cold.
