Searching for relatives who emigrated to North America in the late 19th or first half of the 20th century is a highly structured process, relying on the high level of preservation of foreign archives. Unlike Eastern European archives, which often suffered from wars and regime changes, American and Canadian records are almost entirely digitized. The primary challenge for researchers is identifying individuals among millions of people with the same last name, taking into account the inevitable transformation of surnames in the English-speaking world.

Collection of primary data and work with family archives
Research must begin within the family, systematizing the available information. In North American genealogy, three parameters are critical: the precise spelling of the family name prior to immigration, the approximate date of arrival, and the location of initial settlement.

Data sources within the family archive:

• Letters and envelopes: Postmarks indicate a specific post office, which narrows the search to a county or city.
• Photographs: Photographer's marks on the back of photographs often contain addresses in New York, Chicago, or Toronto.
• Financial documents: Money order or parcel receipts contain the sender's exact address for use in City Directories.

Passenger manifests and ports of arrival
For most migrants of that period, the route to America lay across the ocean. The main gateways to the United States were Ellis Island in New York (since 1892) and Castle Garden (before 1892). In Canada, Pier 21 in Halifax played a similar role. Passenger manifests are the foundation of the search, as they recorded information at the moment of border crossing.

What can be learned from the manifest:

• Last place of residence: A specific village or parish in Europe was indicated.
• Next relative in homeland: The name and address of the person who remained in Europe (the main marker of family identification).
• Receiving party: The name and address of the person the immigrant was traveling to.
• Port of departure: Hamburg, Bremen, or Liverpool, which provides access to European lists.

Census and Naturalization
The US Census is conducted every ten years and allows us to track family dynamics. Researchers currently have access to complete archives from the late 18th century to 1950. Censuses provide insight into family composition, occupation, and homeownership status.

Key citizenship status markers in censuses are critical for determining an ancestor's legal status. The abbreviation "Al" (Alien) indicates that the individual was officially an alien at the time of the census and had not yet begun the citizenship process. The "Pa" (First Papers) marker indicates the filing of a "Declaration of Intent," the first legal step toward obtaining a U.S. passport. The "Na" (Naturalized) status confirms that the citizenship process has been fully completed, providing the researcher with a direct basis for searching for the final "Petition for Naturalization" in federal or local archives.

The naturalization process is the most detailed biographical source. Petitions recorded the exact date and place of birth, date of arrival, name of vessel, and complete information about spouses and children. Documents from the 1920s often contain photographs of applicants.

Specifics of Canadian Archives and Land Records
The Canadian record-keeping system is centralized at Library and Archives Canada (LAC). Many immigrants came to Canada for free land in the west of the country as part of the Prairie Settlement Program.

Search Features in Canada:

• Homestead Records: Land grant records, including descriptions of buildings and personal statements of farmers.
• Prairie Censuses: Special censuses of Manitoba, Saskatchewan, and Alberta (1906, 1916, 1926), critical for the Ukrainian diaspora.
• Border Crossings: Records of movement between the United States and Canada, if the family changed countries of residence after arrival.

Military Records and Obituaries
Participation in the World Wars left a trace in the form of Draft Registration Cards. Even if an ancestor did not fight, they were required to register, providing their address, place of work, and the name of their next of kin. Obituaries in local newspapers are an indispensable resource for finding people who died in the second half of the 20th century.

The value of obituaries as a source:

• Family connections: Listing of all surviving relatives and their cities of residence.
• Biography: History of moves, membership in trade unions and religious communities.
• Burial location: A link to a cemetery, where the place of birth in Ukraine was often carved into the tombstone.

Useful resources and tools for searching
For effective research, it is recommended to use a combination of free government archives and commercial genealogical databases:

• FamilySearch: The largest free resource containing digitized US and Canadian censuses, as well as church parish records.
• Ancestry: A paid resource with the most comprehensive database of military records, naturalization cards, and a handy family tree tool.
• Ellis Island Foundation: A specialized database of passengers who arrived via New York.
• Find A Grave: A global cemetery archive where you can find headstone photos and life dates.
• Library and Archives Canada (LAC): The premier resource for searching Canadian land grants and military records.
• Chronicling America: A free archive of US historical newspapers for searching mentions and obituaries.
