They Came in Ships: The One Book Every Genealogist Researching Immigrant Ancestors Needs
They Came in Ships: If you’ve ever stared at a brick wall trying to trace an immigrant ancestor back to their homeland, you know the particular frustration that comes with it. You know the name. You know the approximate arrival date. Maybe you even know the port. But finding the actual arrival record, understanding what it contains, and knowing how to use it to push your research further? That’s where so many of us get stuck.
That’s exactly why John Coletta’s They Came in Ships: Finding Your Immigrant Ancestor’s Arrival Record (3rd Edition) has earned a permanent place on my research shelf, and why I recommend it without hesitation to anyone doing immigrant research.
They Came In Ships
John Coletta is one of those authors whose name carries real weight in the genealogy community. He brings both scholarly rigor and practical clarity to a topic that can feel overwhelming, and They Came in Ships is a perfect example of that balance. This is a book written by someone who understands the research process deeply and respects the genealogist who is doing the work.
The book focuses on helping researchers locate and interpret passenger arrival records, which are among the most important document types we have for tracing immigrant ancestors. These records changed significantly over time, reflecting shifts in immigration law, government policy, and record-keeping practices. Coletta walks readers through those changes in a way that actually makes sense, giving you the historical context you need to understand what you’re looking at and why it matters.
This third edition reflects updates that keep the guidance current and relevant, which is important given how much the landscape of online genealogy resources has changed over the years. Coletta doesn’t just tell you that records exist. He helps you understand how to find them, how to read them, and how to extract maximum research value from what you discover.
They Came In Ships: The Kind of Guidance That Changes Your Research
One of the things I appreciate most about this book is that it respects the reader’s intelligence while still being accessible. Whether you’re just beginning to tackle immigration research or you’ve been at it for years, Coletta gives you a framework that holds up. He covers the major eras of immigration and the different types of records associated with each period, helping you calibrate your search strategy based on when your ancestor arrived.
Understanding the difference between what a pre-1895 passenger list contains versus what a post-1906 record reveals, for example, can completely change how you approach a search. That kind of grounded, practical guidance is what separates a truly useful reference from one that looks good on a shelf but doesn’t move your research forward.
If you’ve been piecing this information together from scattered blog posts and forum threads, I’d encourage you to stop and invest in a resource that brings it all together in one authoritative place. You can grab your copy of They Came in Ships on Amazon right here, and I think you’ll find it pays for itself the first time it helps you crack open a research problem that’s been nagging at you.

The AI assisted in generating an early draft of the content, but every paragraph was subsequently reviewed, edited, and refined by me. The final content is the result of extensive human curation and creativity. I am proud to present this work and assure readers that while AI was a tool in the process, the story, style, and substance have been carefully shaped by the author.
