Read the evidence docket
- Maya Rivera is the focus person.
- Elena Rivera and Jordan Lee are Maya’s parents.
- Rosa Rivera is Elena’s mother; Sam Rivera is Elena’s father.
- Avery Lee is Jordan’s father.
- No source in this case names Jordan’s mother.
Evidence rule: A blank is not a failure. It shows where the next investigation begins.
Map the three visible generations
Write each supported name in the correct position. Use Unknown once.
Grandparent row · four positions
- Elena’s mother
- Elena’s father
- Jordan’s mother
- Jordan’s father
Parent row · two positions
- Maya’s parent
- Maya’s parent
Focus row · one position
- Focus person
Follow the branching pattern
Each pedigree position can branch to two parent positions.
| Generation | Focus | Parents | Grandparents | Great-grandparents |
|---|---|---|---|---|
| Positions | 1 | 2 | 4 |
These are chart positions, not always unique people. Real family structures and repeated ancestral lines can make a tree more complex.

- I can explain why “Unknown” is stronger than a guess.
One decision I can explain:
