Error 106 Duplicates between global tree and unconnected This unconnected profile has the same full name, birth and death date as an other unconnected profile. These two profiles are probably duplicates and need to be merged and with this action an unconnected tree is connected to the global tree. They can already be connected to global tree, because the global tree for error checking is smaller due to connections in private profiles.
