Merging all Carlberg trees

There are multiple trees with Carlbergs in them. Is there any interest from you all to collaborate, instead of everyone having their own tree?

What makes things worse is that some of those trees are partly merged. Either they should be completely merged into one big tree, or they should be completely separate. As it is now, it's a big mess, where some people appear as siblings to themselves.
