Many Czech and Slovak American families say, “Our name was changed at Ellis Island.” It is one of the most repeated family stories, and it is almost certainly not what happened. Names did change, but the changes came from the families and from the way records were written, not from officials. This guide explains what really happened, the usual patterns and how to recover the original name, which is the key to the registers. We checked these details in October 2026, and laws, statistics and tools change, so confirm them before you rely on them.
The Ellis Island myth
Smithsonian Magazine reports that it is a persistent myth that Ellis Island inspectors altered the birth names of immigrants, and that inspectors were not responsible for recording immigrants’ names. Passenger manifests were created in Europe, usually at the port of departure, by steamship companies, as the New York Public Library and genealogists explain, and inspectors used the manifests to check identities. Czech and Slovak ports of departure were Hamburg and Bremen, so the names on manifests were written there. See our guide to emigration to America.
What did change
- Diacritics were dropped. Růžička became Ruzicka, Čermák became Cermak and Dvořák became Dvorak, according to a Czech-American genealogy tool.
- Spellings were adapted phonetically. SCH or SH replaced Š, CH or CZ replaced Č, and W or F replaced V, so that Vašíček became Vashichek and Vomáčka became Womacka.
- Translations were rare. An older article gave examples such as Tesař and Truhlář becoming Carpenter, and the American Ancestors article notes that an occupational surname could become its English equivalent, such as Jehlička, “needle,” becoming Taylor. The tool, however, says that translations such as Novák to Newman are rarely used and that most names only change spelling.
- Given names were converted. Czech first names often have English equivalents, such as Anna for Ann, Kateřina for Katherine and Alžběta for Elizabeth.
- Magyarized names. Slovak families may have had their names in Hungarian form before they left. See our spelling guide.
A genealogy article on immigrant name changes says that in the United States around 1900 there were no rules about names, so immigrants could alter their names as they wished, and that a name with too many syllables might be shortened.
Where the original name survives
- The passenger manifest. It was written in Europe, and it usually names the village. The Hamburg lists survive for 1850 to 1934, and few of Bremen’s survived.
- Naturalization papers. Declarations of intention, called “first papers,” often name the town of origin, according to Family Tree Magazine. After 1922 married women have separate naturalization records, and children under 16 appear on their fathers’ records.
- Church records in America. Baptisms, marriages and funerals may list the ancestral town.
- Tombstones. Women’s surnames on tombstones may carry -ová.
- Czech census margins. A note may record a passport to America. See our guide to censuses.
A method for recovering the original
- Collect every spelling in US records, including the last one.
- Find the passenger list and compare names, ages and villages.
- Check the naturalization papers for the earlier form and the place of birth.
- Ask older relatives how the name was spelled and pronounced in the old country.
- Restore the diacritics and test phonetic reversals, such as SCH to Š. A genealogy tool can add diacritics to names that occur more than ten times in the Czech Republic.
- Search the registers under the restored forms and the feminine forms. See our guide to women’s surnames.
Why it matters
You cannot search the Czech or Slovak registers under an American spelling and expect to find the family. The registers hold the original name and the village, and the archives need both. Once you recover the original, go to how to find the village of origin and the complete tracing guide.
Illustrative composite (not a real family): A reader’s family name is Womacka, and the family says it was changed at Ellis Island. The Hamburg passenger list, written in Europe, gives the name as Vomáčka with a Moravian village. The census for that village in 1880 lists the household, and the parish register confirms the baptism.
Questions to ask older relatives
- How was our name spelled in the old country, and how was it pronounced?
- Did anyone change it, and when and why?
- Which village did the family come from, and what language did they speak?
- Do any papers survive, such as passports, baptism certificates or church records?
- Is there a gravestone with the original form of the name?
Using naturalization records well
Family Tree Magazine advises checking naturalization records, especially declarations of intention, called first papers, because they may give the town of origin. Note that after 1922 the federal government began keeping separate naturalization records for married women, and children younger than 16 appear on their fathers’ records, so look for a woman’s own file as well as her husband’s.
A caution about family stories
The story of a name changed at Ellis Island may preserve something true, such as a respelling by a clerk in a later record, or a change the family made to fit in. Treat the story as a clue to look for the change in the records, and look for the original in the manifest and the registers.
Common mistakes
- Blaming Ellis Island. Check the manifest.
- Searching the registers under the American spelling. Use the original.
- Assuming the name was translated. Spelling change is more common.
- Ignoring the feminine form. Women appear under -ová in some records.
- Stopping at the arrival record. It names the village, but the registers prove the family.
