A. Twenty-five percent of immigrants did not get naturalized, or even apply for “first papers” (also called a a declaration of intention, the first step in the naturalization process). Females and children were automatically naturalized under their husband or father until 1922—learn more about women and naturalization in this article from the National Archives’ Prologue Magazine. But a widow may have applied for naturalization on her own.
The passenger list should normally be in the book series Germans to America. Unfortunately, I do not find Rosalie and her sons listed.
New York was by far the major port of entry for US immigrants, but other ports are possible, such as New Orleans for someone going to Nebraska (up the Mississippi River). You’ll find a free index for New York arrivals from 1820 to 1892 at CastleGarden.org. Also check the immigration records collection at Ancestry.com, which includes indexes and records for nearly every US port. It may be necessary to view microfilms of ships arriving in March 1877 in New York.
Hamburg and Bremen were the largest German ports of emigration, but the Bremen lists no longer exist. One source that might simplify your search is the Hamburg Direct index, containing the names of those passengers on vessels that sailed from Hamburg directly to an overseas port. Learn more about the Hamburg Direct index at Genealogy.net. A bonus to this index is that if your ancestor is on it, you also find the last place of residence in Europe listed. Ancestry.com has passenger departure records from Hamburg, and the Family History Library has it on microfilm.
