Hey everyone,

I've always been fascinated by how historical traits and medical conditions cascade through family lines, especially the "Royal Hemophilia" gene that Queen Victoria passed down to the Russian, Spanish, and German royal families.

I was getting really frustrated with mainstream genealogy sites—they charge crazy $25/month subscriptions, they have terrible privacy policies, and they don't let you visualize metadata like medical history or DNA right on the tree.

So, I spent the last few months coding my own completely private, browser-based generator: **Radial Roots**.

**The Data:** I used historical records to map 4 generations.  
**The Tool:** Radial Roots (radial-roots.com). It processes 100% locally in your browser (no databases, no creepy data harvesting).  
**The Output:** It generates these massive circular trees where you can track up to 2 custom metadata points per person (I used "Nicknames/Titles" and "Medical History" for this one).

It's totally free to build your tree. If you want to export massive 60-inch print-ready PDFs, it's just a one-time $5.99 flat fee. No subscriptions.

Would love to hear what hardcore genealogists and data nerds think of this radial format!
