Jons and Marit Jonsson (Hedberg?)

From information obtained from a Kinship Center in Sweden, this family of four (Jons and Marit with children Peter Johan and Kerstin) left Varmland Sweden to board the Statsraad Brock in May 1869. I am assuming the information here is different from that of the Kinship Center. I would like to verify that they were on the ship, and any other detail that may exist from the passenger list. Eventually they changed their name to Hedberg, we do not know when or why, so I am curious what name was used on boarding. Thanks very much, Peter Lee
