This project aims to gather together the Geni profiles for all of the notable figures who have been featured on the genealogical television program Who Do You Think You Are? The program has been broadcast in dozens of countries and has many national versions, all of which are included in this project.
When you add a profile for someone featured on the program, please make sure they are listed and linked below by editing this page as necessary.
Style Notes: When you find a profile on Geni but don't have editing access, please link it here so another collaborator can add it. When you are able to add a profile yourself, please put the profile name in bold so people know it has already been added. Please also include a brief description of why the person is notable when adding them.
