JoAnn, Thanks for the suggestion, but the ship arrived 3-18-1890 before Ellis Island on-line records and the only Werra manifest on the website is for 1892. So I am still looking for a passenger list from the 1890 arrival. Thanks, anyway!
Castle Garden closed on April 18, 1890 and until the Ellis Island Immigration Station opened in 1892, all passengers were processed at the Barge Office in New York Harbor. Here is a good site for Castle Garden information:
