Bethgem, I hope you and the other good folk don't mind me jumping in on your thread, especially as it's my first post.
Iv'e done research on my family (which are Scots and Irish) and got back to the late 1700's.
I have now started on my good lady's side of the family and found out that her GGGF Christian Frederick Wall was also a pork butcher (in Carlisle) and is noted as a German National on the1901 census. His estimated dob is 1872.
I have studied the posts and threads on here referencing German Ancestors, and it is indeed a bit of a nightmare trying to find German Ancestry (worse than trying to find your Irish Ancestry).
The Cronem Conference notes were very interesting, and I have indeed, went on all the recommended websites and links that you guy's have shared before posting this thread, and must thank you all for sharing such information.
I did find a passenger on Ancestry.de and Ancestry.co.uk with the name of Christian Frederick (Friedrich) Wall, but this guy has a birthdate of 12/04/1867. A 5 year difference but very possible the same guy. Born in Owen in Kirchheim, Württemburg, application date July 1889, number 835948.
A long shot that this might be the guy, but what to do next, as I believe that the passenger list is practically impossible to decipher.
Again, as per many posts, any further little tips on the above, may open up a further clue to the birthplace of Christian Frederick Wall
Best Regards
John
