Private User --- hello! On Geni, unlike most other genealogical sites where you can enter you family tree, we have one Tree, rather than many separate ones.
It's possible to have a separate tree, but only if it is VERY small.
Other than that, it gets merged into the big Tree by other users connecting branches.
Now, there may have been some mistakes -- if so, you can try contacting the manager of the profiles in question, or go on over to the Discussion forum -- pinned up at the top of the forum is a thread where you can ask for curator help.
If there is a profile that's been merged, or had information changed, you can see the history of that profile by clicking on the Revisions tab.
You now have thousands of cousins -- and that would be normal for Geni.
