Robert, the best way to use that yDNA test information on WikiTree is to invite the yDNA test takers to join WikiTree, and add their own yDNA test information to their profiles. Then either they or you can add profiles for their male line back to their earliest known ancestor. As you can see on your own profile, and on your male Petty ancestors' profiles, WikiTree automatically displays the yDNA test information on the profiles. Anyone interested, seeing that yDNA test information on their ancestors' profiles, is made aware of those tests.
