I should be able to speak and read German, but I can't/ My maternal Grandmother wss a Kunz. The Kunz family, my Great-Great Grandparents, and their first 3 children came to American in the 1860s from the grape growing and wine making area near Heidelberg. Great Great Grandma was a Wiengartner (sic).
Wiengartner => Wenninger (had to go look it up, and now I'm looking at a couple of different photos of her, GG Grandpa Kunz and of their 10 kids who survived to adulthood.
