CD Lookup Please - Zetterberg, Carl Petter

[Sue Thomas]

I am looking for family descendants and information on my Great Great Grandfather Carl Petter Zetterberg born 1800-1835.  He was a Tailor.  
 
Carl Petter was the father of my Great Grandfather Carl Emil Alexander Zetterberg born 15 June 1850 in Uppsala.  Carl Emil a sailor, emmigrated to Australia leaving all his family in Sweden.
 
Any information on Carl Petter and his family I would be most grateful as there are no surviving relatives in Australia who can help me trace our ancestors.
 
I am open to all suggestions.
 
Many thanks
Sue
