Fantasy family tree maker
Free fantasy family tree maker for worldbuilders.
A fantasy family tree maker is a worldbuilding tool for charting dynasties, noble houses, and bloodlines — the succession-critical relationships that hold an invented world together. It handles what real genealogy software refuses to: centuries-long lifespans, half-elven parentage, polygamous royal lines, and successions that jump branches.
Built for this kind of family
Dynasties and houses
Map each house as its own branch or file, and chart the marriages that bind (or doom) alliances between them.
Long-lived races welcome
No birth-date validation complaining that an elf is 600 years old — your world, your rules.
Succession at a glance
Generational rows make claim-lines readable: who inherits, who was passed over, where the cadet branches split.
Campaign-ready
DMs map NPC noble families for intrigue arcs; players keep their character’s lineage canon between sessions.
How it works
Found the dynasty
Start with the founder and build the ruling line downward, generation by generation.
Marry the houses
Add inter-house marriages and mark the alliances, feuds, and betrayals between branches.
Chart the succession
Mark deaths, disinheritances, and claims — the tree becomes your world’s political map.
Frequently Asked Questions
Can it handle non-human lifespans and races?
Yes. There is no validation forcing realistic birth years or two-parent biology — chart 800-year-old elves, half-dragon parentage, or divine ancestors as your canon requires. Labels and notes carry whatever lore each figure needs.
How do I show a contested succession?
Use relationship overlays: mark the rightful line, then add conflict or cutoff lines for usurpers and disinherited branches. Deaths get the standard deceased marker, so living claimants stand out immediately.
Is it useful for D&D or other TTRPG campaigns?
Very — DMs map noble houses for intrigue-heavy arcs and keep NPC relationships straight across sessions, and players document their character’s ancestry. Share a read-only version with the table, or keep the DM-truth version private.
Can I start from a template?
Yes — open the 3-generation template and extend it downward as your dynasty grows, or describe the royal line in text and let the AI draw the first draft.
Your characters deserve a canon
Free to start. Describe the family, watch the tree appear.
