Question

On my main family tree page it won't let me delete multiple trees. Why it won't let me delete a tree.

Answer 1

Just press "remove"

Answer 2

Can you tell us what you're seeing when you do this:

1. Click on "My Account" in the upper right.
2. Click on the "Remove" button to the right of the family tree you want to remove.

When I do that, I get a pop-up that confirms the deletion and then the tree is removed from my account (but is not removed entirely if I have shared it with anyone else).
