"Caravan11" asked if the Wilhelm Langes to whom I am related could have served in the 26th Wisconsin Infantry in the Civil War. It is not possible since they did not immigrate to the US until 1891.
There are other Wilhelm Langes in the Waseca County area during the same time period. Try writing to those who know more about them.
I am interested in your comment on Samuel Prochel (usually PROECHEL). I have studied his parents and family both in Posen, Germany (Samotschin, and in Radsitz (=Hermannsdorf)) and in Minnesota, especially Waseca County. What information do you have on Samuel's military service? Thanks for any info on him. All the best,
