Re: Ferdinand Jahns and Pauline Saupe (CLAUSSENS)
Thanks for your email.
My Claussens were from the Island of Fehmarn.My gr-grandfather, Julius Claussen, emmigrated to Chicago ~1865 from Westermarkelsdorf on Fehmarn.At the time, this was part of the independent Duchy of Schleswig (closely affiliated with Denmark), though now the island is part of northern Germany.
As to your Claussens, I do not know about Louisa or Wilhelm Wünder/Wunder/Wonder.I do not believe that they are cousins (or at least close ones!) to my Julius.
I have two suggested sources of further research for you.
The first one is the national Danish database shown at the site below.They have done a great job at pulling together Danish census information and they are starting on emmigration information.
A couple of words of caution for you:
1.Claussen was a pretty common name, especially in the counties of Schleswig and Holstein in the early-mid 19th century.So it will really help if you can find out the town or county that your Claussens were from.Also, be sure to always research Clausen/Classen as name varients.
2.The census DB above is not complete by any means.The most complete mid-19th century census that has been indexed is the 1845 census.But your Louisa was not even born by then so it's not much of a help without her parents' names.Also, my Claussens from Fehmarn are not indexed yet in the 1845 census (though they are found on Fehmarn in the 1840 listings).I looked for your Louisa in Sydslesvig (Schleswig) in the later years (1850-1870) but did not find her.Of course, she could have been from another county or not yet indexed.
If you eventually find them I would then refer you to the following additional DB.This is the most complete DBs that I have found for the 1803 census for the Schleswig region.You can find it at the following link:
The main page for this site is also quite helpful at:
Don't give up!Keep looking.Access every original record you can from their town/county in Iowa and you may find a mention of their home village in (probably) Denmark.A good place to look is at their death certificates.Their POBs may be mentioned there.Also, possibly their parents' names.
