Hi ananymous!
1. Join WikiTree asa member. Set Privacy to show your Public Family Tree which is needed for your DNA test to display.
2. Enter your DNA test(s) on your own profile.
3. Add your parents, grandparents, etc until you can connect to your 4th great grandmother.
4. That’s it. WikiTree programming reindexes each evening, so the next day your DNA test will show on her profile and any others in the genetic line.
