What Lost Tribes can do

Follow leads, compare records and keep track of what remains uncertain.

  • Research assistant

    Ask about a person, place or missing connection. Follow the evidence with further questions as the research develops.

  • Record search

    Search the web and public archives for records that may help answer your question.

  • Name variants

    Lost Tribes checks alternative spellings, maiden names and nicknames to help find the same person across different records.

  • Handwriting and images

    Upload a certificate, census page or letter. Lost Tribes transcribes the handwriting and printed text for you to review.

  • Tree updates

    Ask Lost Tribes to add a person or relationship, then review the proposed change before keeping it in your tree.

  • Listen to your research

    Hear answers and historical transcriptions read aloud with text-to-speech. Follow along as you review records and explore your family’s story.
