Pro Tips
- *Start with a broad database, then verify findings in archive-based sources or original images.
- *Search multiple spelling variants, initials, translated names, and phonetic versions of the surname.
- *Use port, ship, and arrival year filters instead of relying only on an exact name search.
- *Check whether your ancestor's destination country created both arrival records and naturalization records, as each may reveal different details.
- *Combine immigration databases with country-of-origin archives to confirm birthplace, last residence, and family relationships.
