One of the first things most people do when starting a family history project is research their own surname. And, even though we can only learn a small part of our family’s past from doing so, it is always a fascinating undertaking. Our surname ties us to the generations who came before and it can be great fun to know where that name originated.
If you are lucky enough to have an unusual surname, it can also make your search of the past a little easier (or harder, depending on who you ask). After all, there were certainly more women named “Mary Brown” than “Mary Niedergeses” in old records. But even if your last name is common you are likely lucky enough to have a few rare gems in your family tree as a whole. If you have been doing research for a while, you know which ones they are.
Curious as to how rare these surnames really are? If so, many of you have probably used Ancestry’s fun tool to see how the distribution of various surnames has changed throughout American history (with data available between 1840 and 1920), but did you know that the U.S. Census Bureau provides more recent information on surname usage?
The Bureau has been keeping track of the frequency of surnames reported by Americans every ten years, and has compiled Census Surname Tables for the 1990, 2000, and 2010 census returns. You can download the latest data, a spreadsheet of surnames and the exact number of those claiming them, right here.
Interestingly, the five most common American surnames as of 2010 haven’t changed that much over time and are Smith, Johnson, Williams, Brown, and Jones. But the bureau also compiled lists of the fastest-growing surnames in the United States and these include Zhang, Li, Ali, Liu, and Khan – a testament to the wonderful diversity of our nation.
According to the bureau’s data, there were nearly 6.3 million distinct surnames in the United States in 2010 and while they don’t, unfortunately, share the rarest of these names (those that belong to less than 100 people), they do share those last names with only 100 entries each.
The list below is a selection of these rare names, of which there are just over 1200. To see them all you will need to download the complete list here and scroll to the bottom to locate surnames held by the least amount of people.
