Relationship Prediction Refinement Project

Predicted relationships between matches can be an important clue when verifying trees, working on brick walls, or searching for family.

Differences in the algorithms and chips affect both the amount of shared DNA reported and the predicted relationship - making research harder.

We’re asking for your help. Using the data you submit, we will help the genetic genealogy community understand these impacts and update our Relationship Estimator (web-based soon!) and Prediction Charts.

PRIVACY: None of the individual data submitted will be made public.

They will be handled in accordance with our Privacy Policy

To participate, you will need to know:

1) The chip for both the tester and the match (see below for how to determine the chip)

2) Total Shared CM, # of Segments, and Longest Segment (longest segment does not appy for AncestryDNA)

3) The actual relationship

We would like the following but you can still participate if you don't know

1) The company's predicted relationship or predicted relationship range

2) Paternal or maternal side

3) Is there endogomy?

4) Are the testers' parents or the match's parents 4th cousins or closer?

Please only report on matches where the MRCA and relationship has been confirmed.


For ancestryDNA users

Please do NOT report "Shared DNA Hints" without the research and confirmation of the Most Recent Common Ancstor (MRCA)s and actual relationship.

The link to this article on Kitty Cooper's Blog explains why this is important.
