Though American family records may not extend as far back as most British or Irish records, their breadth and detail is still impressive.

For such a relatively young country, its historical records are surprisingly rich, giving you an intimate look into the lives of your American connections.

1. Birth, marriage and death records

The building blocks of any family tree, on Findmypast you can delve into millions of US births and baptisms, the largest online collection of US marriage records covering 360 years and more than 450 million names, and millions more deaths & burials.

2. Census records

US census records are unlike any other resource in terms of detail. In fact, the US was the first nation to make censuses a mandatory part of its constitution.

The federal censuses, taken every 10 years between 1790 until 1940, are all available to search on Findmypast. That's almost 700 million records. Due to privacy laws, the 1950 Census won't become available until 2022.

3. Travel and migration records

US passenger lists contain records dating as far back as the 1600s. If your ancestor emigrated to the Big Apple between the mid 19th and the mid 20th century, you'll likely find them in our collection of New York Passenger Lists & Arrivals. Don't forget, if they headed to America from the UK, you may also find them in Passenger Lists Leaving UK 1890-1960.

If your ancestors were US immigrants, have a look in Findmypast's exclusive British & Irish Roots Collection. It features everything from passport applications to photographs.

8. Catholic Heritage Archive

Catholicism is the largest religious denomination across America and Findmypast's unique Catholic Heritage Archive allows you to trace your family's Catholic roots across the states and back to the British Isles.

10. Global records

We often think of American ancestors from the perspective of their settlement in the new world but many also made lives for themselves overseas. Did they travel to Europe or the Caribbean? Did they live or work down under in Australia or New Zealand? Billions of international record collections on Findmypast could be hiding intriguing stories about ancestors who left America behind.
