The most direct mark you can make is simply to identify yourself.
You can use your full name and birthday, such as "Helen Rose Walleck 1939-8-27"
or add titles like "Helen Rose Walleck 1939-8-27, graduate of Pittsburgh University,
pioneering computer programmer, and financial planner."
To help future genealogists, you can provide your parentage.
For example, "Helen Rose Walleck 1939-8-27 of Frank Joseph Walleck and Marian June Silver".
There's no limit to how many ancestors you can provide; you choose.
