Was wondering do you have a John Kop/Kopp in your family records or a Charles Kop/Kopp. John went to Dubuque, Iowa and Charles was listed as living in Minnesota, when John died. John and Charles are brothers. They came from Alsace-Lorraine, Germany to avoid going to war.
Please let me know if this is the same Kop/Kopp line. I have some more information if you need it.
John changed the spelling to Kop when they came here and then my great grandfather changed it back to Kopp, that is what i'm told from my grandfather.
