Your latest message was directed to me I suppose because I once put a small point about German spelling which seemed to be puzzling people on the board. Back to your original question. I would think there is a good possibility that your ancestors used what was known as the "indirect route" - google will give you a lot of links. Put shortly a vast number of emigrants, particularly from Poland and Russia left from Baltic ports - Libau (Liepaja), Memel (Klaipedia)Danzig (Gdansk), Gdynia. They bought a through ticket from home station to ship - to England (mostly east coast ports), rail ticket to Liverpool, Glasgow or Leith mostly for North America, Southampton for Australia or South Africa. The stream was so big that a special station solely for emigrants in transit was built in Grimsby in addition to the "ordinary" station. Ships from Hamburg and Bremen also used this route the main reason being that it was much cheaper than taking the regular service big line trans-Atlantic ships. The main shipping line involved in the Baltic runs, especially from Scandinavia, was the Wilson Line which almost had a monopoly on the trade. It could well be worth investigating these routes and don't forget that Bremen itself, as well as Bremerhaven (two different places!) also took a lot of emigrant trade - it wasn't just Hamburg. Hope these ideas have some use for you.
