Looking for a rare or hard-to-find family name? This searchable surname index includes more than 100,000 unique surnames compiled from local libraries, historical societies, and genealogical organizations across the United States and Canada. Much of this material was gathered at the local level, meaning these records may not be available anywhere else online.

This is your chance to uncover hidden resources tied to your family name—whether it’s an obscure branch or a well-known line with deep roots.

  • Surname: The surname that is the focus of the surname folder found in a library or repository.

  • Repository: The name of the organization or repository you should contact for more information about the surname you are researching. You can either visit the repository listed, or it may be more convenient to write for more information. Some addresses may have changed since this information was compiled over 20 years. You may wish to confirm the address (perhaps at a local library or on the World Wide Web) before visiting or writing the organization or repository.

  • State/Province: The state or province where you can find the repository or organization that holds information on the surname you are researching.
