Pedigree Resource File (PRF) is a growing collection of user submitted genealogies. It shows individuals’ names; family relationships; and dates and places of birth, marriage, and death. No merges, corrections, or additions are made to genealogies submitted to Pedigree Resource File.

When to Use It

Use Pedigree Resource File to discover what genealogical research has already been done. Use it to guide you towards original records. As with all compiled genealogies, Pedigree Resource File has significant limitations (see below) and more accurate information should be sought from the original records.


  • Submitters are responsible for the accuracy of the information. FamilySearch does not check the accuracy of any contributed genealogy.
  • Information in Pedigree Resource File is second-hand. Verify the information before accepting it.
  • Submitter information, previously available, is now hidden for privacy reasons.
  • Pedigree Resource File contains many errors and unlike the new FamilySearch Tree, corrections are not accepted. Submitters are advised to make another submission that includes corrections. However, both old and new submissions are left in Pedigree Resource File.

Submitting Your Genealogy

Sharing your genealogy allows you to preserve your family history in the Pedigree Resource File and share it with others around the world. A copy of the genealogy files (GEDCOM format) that you submit will be preserved in the Granite Mountain Records Vault located near Salt Lake City, Utah. In addition, your genealogy may be made conveniently available to others on the Internet.

You can quickly and easily submit your genealogy:

  1. First, obtain permission from any living persons mentioned in your genealogy to submit their information to FamilySearch. Remember, notes and sources attached to an entry for a deceased person may also include information about a living person. For privacy reasons, you must remove any information about living persons if you do not have their permission to submit it.
  2. Second, review your notes and sources to make sure they don't contain any offensive or inappropriate statements about another person. If found, remove such information.
  3. Third, save your genealogy in a GEDCOM file format on your personal computer. Many genealogy software programs provide the capability to save your records in a GEDCOM file format (where the file is named with a .ged extension -- for example: eastleyhistory.ged). Please see the instructions provided with your software for more information.
  4. Fourth, submit the GEDCOM file that you have created to FamilySearch. You will need to agree to the conditions for submitting your genealogy before submitting the file. For instructions, see Submitting to the Pedigree Resource File.
