What is a Public Tree Person?
A YourRoots Public Tree Person is a tree person based on aggregated data from family trees uploaded to the YourRoots network.
Our system scans the entire tree network and detects tree persons shared between multiple trees uploaded by different tree owners.
Using our proprietary algorithm and AI tools, we evaluate Public Tree Person matching based on name, birth date/location, death date/location, and parents/descendants matching.
We regularly update our database to produce more Public Tree Persons.
