I assume you are referring to the article about Carl Johan, "Tidning för Wenersborgs stad och län" for 14 May 1856". I didn't look for him since this event was some 16 years after I last have evidence of where Erik Gustaf was living. And as we discussed before, the last information was that he had applied for permission to travel to England in 1840.
After 16 years, I wouldn't know where or how to look for him in Göteborg. Also, as the article points out, Carl never found him there. If you have some search tips I would really like to find out what happened to Erik.
