Often the process of going back over records you’ve seen many times can be very fruitful.
Tonight I was looking at the German passenger list for the Zierke family, who came to America from Prussia in 1865 aboard the “Neckar”. Curiously, a transcription for the town where the family had come from had been added, and it said “Jablonowo”.
One thing I’ve come to learn about the German passenger list transcriptions on Ancestry… they are usually pretty good. The people who do them seem to be experts in German handwriting of the 19th century, and they are often able to pull out information that would not be apparent to English-speakers.
So I looked up Jablonowo, and almost immediately I saw one entry from Kreis Kolmar. This was quite interesting to me since the Hadow and Willegal families were from Kreis Kolmar, as was the Schulz family, as was the Zierke family who immigrated to Princeton, Wisconsin. All four of these families are linked to my Zierke family in some way. Some circumstantially, others definitively.
This map shows the proximity of the towns where these families came from. The Hadow/Willegal family is highlighed in yellow. The Schulz family is highlighted in green. The Princeton Zierke family is highlighted in blue, and Jablonowo is highlighted in purple. If Friedrich Zierke did marry Dorothea Hadow as I believe, you can see how close those towns are to each other. From Usch-Neudorf to Jablonowo is only 3 miles!
