I am looking for someone who traces their Bank line back to Karl Bank in Chicago. He was born in Hohenmocker, Kreis Demmin, Pommern, Germany and his sister, Caroline, was married to Helmuth Kasch. The Kasch family emigrated to Chicago, IL from Germany in 1867. I don't know when Karl Bank emigrated, but he was a witness at the christening of a son of Helmuth and Caroline in 1881.
Caroline had three brothers that all had Karl/Carl as one of their three given names, so I don't know which one it was.
If anyone can give me any information on this family, I would be grateful.
My email address is firstname.lastname@example.org
Thank you, Julia Kasch
