Good question - thanks for asking it here.
Let me suggest that you go to your oldest known ancestor on WikiTree (that person's Profile Page) where you are on the Trusted List or where the Profile's Privacy is set at "Open".
On that page, just below the row of file tabs (Profile-Edit-Photos-FamilyTree-etc) is a row of smaller, rectangular buttons with icons in them. Click on the one marked 'Descendants' with the little green squiggle icon behind it.
That will only give you five generations, but will include all those cousins that are on WikiTree.
I hope this helps,
