My husband is 3/4 German. He's been working on his genealogy and has been unable to get a connection across the ocean. He did learn that one relative came over from Bavaria. He has been able to find nothing on his ancestry in Germany. He can't read the German script and very little information seems to be indexed.
We've been to Germany a couple of times. The last time there we went to see the model railroad in Hamburg. It's incredible. They had completed the airport, and we got good videos of everything. We drove down to Hamburg from Demark just to see the railroad. I'm half Danish and half Norwegian. I feel very fortunate. I don't think any other country is as generous with providing genealogy information free. I think I've removed all of my brick walls. Now it's just a case of looking up and recording sources.
I had three major brick walls dealing with great grandparents. But I finally broke through with the help of people on the message board and the Norway list.
