    How to Build Your Family Tree on Ancestry.com

    Trace your ancestors back generations using census records, birth certificates, and your DNA.

    1

    Start a free tree

    ~15s
    Go to ancestry.com and click "Start your free tree." Enter your name, parents, and anything you know about your grandparents. You do not need to pay to start the tree.
    2

    Add what you know

    ~15s
    Fill in names, birth years, marriage years, and locations for every family member you can remember. The more details you give, the better Ancestry can match historical records.
    3

    Watch for the green leaves

    ~15s
    Ancestry marks each person in your tree with a small green leaf when it finds matching records — a census, birth certificate, or someone else's tree. Click the leaf to review and add the record if it is truly the same person.
    4

    Start a subscription if you want more

    ~15s
    A paid subscription unlocks the historical records themselves. Use the 14-day free trial to do a burst of research, then cancel if you are done. US Discovery plans cover American records only; World Explorer covers everywhere.
    5

    Take a DNA test (optional)

    ~15s
    For about $99, Ancestry will mail you a saliva kit. You spit in the tube, mail it back, and 4 to 6 weeks later see your ethnicity estimate and any DNA cousin matches who are also on Ancestry.
