By Patricia Hartley

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, whether it’s a rare one or a name you share with thousands of others, ties us to the generations who came before and it can be great fun to know where it originated. 

If you are lucky enough to have an unusual last name, 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 your surname is? If so, many of you have probably used Ancestry’s fun tool to see how the distribution of various last names 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 last names as of 2010 (data from the 2020 census is not yet available) 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. So we can’t know what the rarest last name is, but we can get close.

The list below is a selection of these uncommon last 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 in the US.

Interested in Researching Your Surname or Those in Your Family Tree?

Researching the origins of last names in your family tree can be a fascinating journey and well worth the effort. We suggest reading What a Surname Can REALLY Tell You About Your Family’s Past first to help you clear up confusions and get you started.

It’s easy to make assumptions about what your family name can tell you about your ancestry if you’re not cautious. Know that a name, no matter how rare, can have many origins. Make sure you take the time to research the line (often paternal in the US, but not always) that provided you with your surname. See where this family line takes you before making determinations about what it may mean. 

How can I research a family tree with rare last names?

Researching a family tree that includes rare last names should be done in the same manner as any other tree. You’ll want to start by interviewing family members for details about recent individuals (parents, grandparents etc) and then enter this information into a solid family tree program. Carefully research each person, adding as much factual data as you can prove (and always record your sources).

Get two full weeks of free access to more than 18 billion genealogy records right now. You’ll also gain access to the MyHeritage discoveries tool that locates information about your ancestors automatically when you upload or create a tree. What will you discover about your family’s past?

As you work backwards in your tree more and more information will become available via your own research and the presentation of record suggestions (if using trees that provide them, see the above linked article about family tree programs for help with this). Sometimes it only takes a few generations before you’ll begin to see where a surname originated – other times you may have to research further back, especially if you have early US colonial ancestors.

Once you can discover an origin for your uncommon last name, you’ll be able to better research the people who carried it and perhaps even locate exactly why it was created (many surnames have fairly recent origins).

Knowing that you only share your surname with a small group of people can be exciting and may help you reveal forgotten stories about your family.

  1. My last name is Gluz… There are approximately 60 in the US. Most of the names on your list that I checked have significantly more… Usoro 84, Ardolf 241, Tartal 111… If you are going to make declarative statements, please do your research first!!!

  2. William Tipkemper

    My surname is Tipkemper. I have distant cousins in Germany. However, except for my immediate family, I have never found anyone else with that name anywhere in the United States.

  3. what about my LNAB: Dreppenstedt I dont believe I can be the only one in the U.S.A with this name at birth. There is a small number with same last name of Dreppenstedt in Nienburg,Nedersachsen,Germany who are distant cousins to me. Thank You,

  4. Charlotte Lynn Ridgely

    My last name is Ridgely. Is this rare? What’s it mean and where is it from?

  5. Well, all language is made up so yes, but more relevantly, the idea of having family names isn’t actually very old. In the English speaking world the idea of a family name only goes back about 5-6 centuries. In much of the rest of the world the concept is even newer, often only going back until colonialism, or isn’t even the same as the English speaking world with people having names that denote their relationship to one or both parents instead of solely patrilineal descent. For example, the Arabic word ibn and the Hebrew word ben both denote that someone is the son of someone. So for example you can have David ben Jesse or Uthman ibn Affan. What looks at first glance like a family name is only the first name of the father. Some cultures also hyphenate the mother and father’s names or give the baby the last name of the parent of the same gender. Some cultures put the family name first, for example Kim Jong-Un and Kim il-Sung.

  6. Not so. The names Ellis Island used were the ones from the ship manifest BEFORE they left shore. Plenty of people changed their names, but not at Ellis Island by wim of the in processors.
