Face Recognition

Dear Copilot Artificial Intelligence  https://copilot.microsoft.com/

Write an article about compare a face on familysearch.org and tell us how accurate it is.


Certainly! Let’s delve into the fascinating world of facial recognition technology and explore FamilySearch’s Compare-a-Face feature.

Facial Recognition Technology on FamilySearch

FamilySearch is a genealogy platform that allows users to build their family trees, discover ancestors, and connect with relatives. One of its intriguing features is Compare-a-Face, which enables users to compare their own faces to those of their relatives. Here’s how it works:

  1. Uploading Photos: Users can upload family photos containing faces. The system then isolates the faces from these photos.

  2. Measurement and Comparison: Compare-a-Face makes a series of measurements based on facial features. It analyzes factors such as the distance between eyes, nose shape, and jawline. These measurements are used to determine how closely related two faces are.

  3. Matching Algorithm: The system compares the uploaded photo to portrait photos of ancestors available on FamilySearch. It looks for similarities and calculates a similarity score.

  4. Interpreting the Score:

Accuracy and Considerations

Now, let’s address the accuracy of Compare-a-Face:

  1. Quality of Photos: The accuracy of the tool depends on the quality of the uploaded photos. Clear, high-resolution images yield better results. Poor-quality photos may affect the accuracy.

  2. Ancestor Portraits: The system matches against portrait photos of ancestors. If an ancestor’s portrait is a tombstone photo, it will compare against that image. Keep in mind that tombstone photos may not capture all facial features accurately.

  3. Negative Matches: Scores below 30-35% are less reliable. However, a low score doesn’t necessarily mean no family connection—it simply indicates a weaker resemblance.

  4. Additional Context: Compare-a-Face doesn’t consider all photos on FamilySearch for a given person. It focuses on portrait photos. Therefore, if your ancestor has other types of photos (e.g., candid snapshots), they won’t be part of the comparison.


In summary, FamilySearch’s Compare-a-Face is a valuable tool for exploring potential family connections based on facial features. While it’s not infallible, it provides intriguing insights into our shared genetic heritage. Remember to use it alongside other genealogical research methods for a comprehensive understanding of your family tree.

If you’d like to try it out, you can access Compare-a-Face on FamilySearch’s website2. Happy exploring! šŸŒŸ


So I tried this program myself. Very interesting.  My father and I have the closest appearance. My paternal grandfather is almost as close, and we do look alike. And as you can see, I also look like many of my great great grandparents.

The program also lets you compare how you look to celebrities. Since we are not related to these people the percent is lower.
