Are you the profile manager? Then you can easily recycle them by changing their names and dates.
Otherwise, do they fit in your tree? What I means is, are they related to the people around them that ARE in your tree? In that case, 'Welcome to the global tree that is WikiTree!'
On Wikitree there are no personal trees, just profiles. We are all part of one big global tree, because we are all related one way or the other. This way you can find distant relatives and ancestors the easy way.
Hope this is what you meant.
