This sound like my relative. Haven't been looking on Ancestry for some time & now I see something on John Eckstein. John Jr. married my great grandmother, Barbara (Novak-Krofta)Simonek. Her parents are George & Anna Novak but on the marriage record, it shows her father as George Simonek and her mother as Anna Novak. I do have a copy of their marriage certificate which I had gotten at Kewaunee Deeds Office some years ago. The son, John, lived with his daughter (Anna Eckstein-Repitz) in his last years.
It's possible that he may have known someone who had told him about the land prior to moving to the US and he purchased the land to move his family onto the land upon arriving to the US. That may have been what brought him to the US with his family. I'm sure the owners didn't care as long as they got their money. I'm hoping to travel to Kewaunee County in mid May. I could ask to see what kind of an answer they give me.
