Ancestry.com has a database on their site of Hamburg passenger lists. That would be those people leaving Germany from the port of Hamburg. Recently there has been an update to the database which includes an index of the records from 1850 to about 1890, I think, anyway is covers the dates I need. The great thing about this index is that it is the Archives in Germany that is doing it. Which means that the information from the transcription will be more accurate.
In my case, I was hoping to see a refinement of the entry for Frederick William John and Henrietta Volk in the records. Which I did. The transcription confirmed that which I believed to be true, but wasn’t quite sure of, F W John and his wife Henrietta both indicated that they were born in Altraden, Posen, Prussia.
It’s not ground breaking news, but it makes me feel better about including the information in my own records. FW’s brother August did not have to give the same information when he emigrated in 1855, he only had to say where he was from, that could just mean where he last lived. We have that information.
At this time there are very few accessible records for Altraden for me to look at. I do keep checking up on Posen websites as there are a few indexing projects going on from church records, but it might be a while before we find anything, if ever.
