What documented migration paths link Swedish-born individuals named Frantzve to U.S. immigration records in the 1920s?
Executive summary
There is no evidence in the reporting provided that links any Swedish-born individual named "Frantzve" specifically to U.S. immigration records in the 1920s; the sources describe broad patterns, shorthand routes and documentary collections that would be the places to search but do not mention that surname [1] [2] [3]. The documented migration pathways of Swedes in the 1920s center on well-established North Sea–British port transit routes, transatlantic steamship lines, and chain-migration corridors into the American Midwest and industrial cities—context necessary to interpret any individual "Frantzve" record but not proof of one [2] [3] [1].
1. What the sources actually document about Swedish migration in the 1920s
Scholarly and archival sources agree that Swedish emigration continued after World War I with a last surge around 1923, then fell sharply after the U.S. Immigration Act of 1924 curtailed quotas; by the mid‑1920s mass emigration had effectively ended and the number of Swedish‑born in the U.S. began to decline [1] [4] [2]. Academic work notes that emigrant selection and transportation networks built up in the late 19th and early 20th centuries persisted into the post‑war period, but economic changes in Sweden and legal barriers in the U.S. reduced flows by the late 1920s [2] [5].
2. The concrete routes and documentary touchpoints one would expect to find "Frantzve" in
Primary migration pathways for Swedes typically ran from Swedish interior parishes to Swedish ports, across the North Sea to British embarkation points (Hull/Liverpool channels noted in emigrant studies) and then on transatlantic steamships to U.S. ports, with many arrivals routed to the Midwest and industrial cities via inland rail networks—these are the channels reflected in emigration registers and passenger lists researchers use to trace individuals [2] [3] [6]. The reporting also points to extant emigration registers (linking Swedish census data to emigration records for 1890–1920) as a documented source that could contain a "Frantzve" entry if one existed in those years [2].
3. Where the archives and registers cited would show a match — and what they do not show in these sources
The Minnesota Historical Society, Augustana/Swenson Swedish Immigration Research Center, and national emigration registers are called out across sources as repositories that preserve passenger lists, America‑letters, and emigration volumes covering the late 19th and early 20th centuries; these are precisely the published collections and datasets a name search would target [1] [3] [6]. The present packet of reporting, however, contains no passenger manifest excerpt, no indexed emigration‑register hit, and no specific mention of the name "Frantzve," so it cannot be cited as documenting that surname’s migration to the U.S. in the 1920s [1] [3] [2].
4. Plausible reasons a "Frantzve" record might be hard to find and how the sources illuminate those pitfalls
Sources explain high rates of return migration in the 1920s and inconsistent name spellings as common complications: a large fraction of post‑1919 migrants later returned to Sweden and many manifests and registers anglicized or misspelled Scandinavian names, which can obscure searches for rarer surnames [7] [3]. The U.S. quota system and the drop in flows after 1924 also mean fewer new arrivals and therefore fewer potential "Frantzve" entries in U.S. arrival indexes for the latter half of the decade [4] [1].
5. Reasoned next steps based on the documented pathways and sources cited
Given the documented routes and repositories, the responsible next steps are to query Swedish emigration registers (1890–1920), Ellis Island and U.S. passenger lists for 1920–1924, Swenson/Augustana collections, and Minnesota Historical Society holdings—searching variant spellings and return‑migration records—because the cited literature and archives are where a 1920s "Frantzve" would most plausibly appear, even though the supplied reporting contains no direct evidence of such an entry [2] [3] [1].
