I do not have anyone by that name, although future decendents of the family have used the name John. If your relative is related they should have been born in same area. I will need to look up your location and see where it is in regards to the information I have. If your ancestor is related he would have been born after Johanna. I will double check on other sites. Maybe when he came in he listed relatives. By the way, he came in same year as my ancestors. Maybe they are related. Don't write it off yet.
