Hi! No, I am not related to Charles Johnson, I was just trying to help you. Because I am Swedish and maybe it is easier for me to check things here.
I live in Stockholm, but there is no place called Horsens here or outside Stockholm. (In Denmark there is a Horsens though)
His swedish name should have been Karl or Carl. The last name would be Johansson, Jonsson, Jönsson or Johannesson.
I did not understand, is 1855 his exact birthyear?
