If your Y-chromosome DNA (Y-DNA) match is not on your Family Finder match list, it may be that the match did not take the Family Finder test. Matches do not work across databases. You may check this on your Y-DNA match list by looking for FF or Family Finder next to the match’s name. If FF or Family Finder is displayed, then your match has taken the Family Finder test.

If both you and your match have taken the Family Finder test but do not match, it means that your relationship is unlikely to be within the past five generations.
