How It Maps
| Cue | Maps To |
|---|---|
| Father/Mother of | Go UP one generation level |
| Son/Daughter of | Go DOWN one generation level |
| Brother/Sister of | SAME level, same parents |
| Husband/Wife of | SAME level, use = sign to connect |
| Uncle/Aunt | Parent's sibling — same level as parent |
Why It Sticks
A visual tree makes impossible-sounding chains like 'father's mother's daughter's son' trivially easy — just follow the arrows.
Frequently Asked Questions
How to handle 'only son/daughter' clues?
'Only son' means no brothers (can have sisters). 'Only child' means no siblings at all. These limit family tree branches.
What about coded blood relations?
First decode the symbols (e.g., A + B means A is father of B), then draw the tree as normal.
