Baden, Germany Emigration Index, 1866-1911 – Free Search
In 1814 the Congress of Vienna recognized Baden as a sovereign member of the German Confederation. For more than 100 years following this event, Baden would be involved in both political and economic turmoil, which led many people to leave the area. While it may take months or years to find an American document stating where an immigrant ancestor was born or resided in Germany, searching emigration records may produce that information in far less time. This index, compiled by the Badischen Generallandesarchive Karlsruhe and microfilmed by the Genealogical Society of Utah, contains the names of over 28,000 persons who left Baden between 1866 and 1911. Each entry includes the emigrant’s name, residence or place of birth, and the year of departure. Wives were not indexed separately unless they traveled alone or with their children. Children who left with one or both parents were not indexed. Some cards state that the person whose name is listed was traveling with “five persons” without naming each individual. The emigration lists were sent from district offices scattered throughout the state of Baden, to one central office. From these lists a card index was developed. This electronic index was translated and keyed from the microfilmed copy of the records. Anyone with ancestry based in this German state should find these records interesting. (A paid database)
Irish Records Extraction Database – Free Search
This 100,000 name database of Irish vital records is unique for two reasons. First, it represents one of the first major databases of records from outside the continental United States. This posting represents the beginnings of a vigorous international content acquisition effort. Second, rather than just raw data, this database is accompanied by a significant amount of contextual and historical information. This information can help researchers understand the significance and the source of the data and also extend their research beyond the names available in the database. (A paid database)
United States Ship Passenger Lists
- Ellis Island
This event, long-awaited by genealogists, will provide easy access to ships’ passenger manifest records of immigrants who entered through Ellis Island. Since it is estimated that 40 percent or more of Americans can trace their roots back to an ancestor who came through Ellis Island, millions may be able to find their immigrant ancestors in these records.
