Hey! These are my ancestors you are talking about!
In north central Indiana there was a enclave of Swabian emigrants, in Benton & Warren counties among others. In Oxford Indiana 'Rommel Park' is named after on of the local families who trace back to a cousin of Irwin Rommels father who emigrated in the later 19th Century. & yes eve today its possible to detect a peculiar handling of the consonants in the speech of the old families in Benton county who have German surnames.
Well, I personally like Swabans, they have an un-aristocratic different way of talking and thinking about the world that one could see in listening to the old speeches of Einstein and Rommel talking about things.
