Once two or more trees have been merged-it is up to everyone in the tree to assist with merging duplicates. Removal of these duplicates may result in loss of lots of hard work.
Therefore, you should merge those. To do so, you may use the ‘Move Person’ feature in the tree (see "How do I drag and drop profiles in the tree to merge duplicates?" for instructions) or the 'Resolve Duplicates' feature in the tree (see "How do I use "Resolve Duplicates" in the Tree?" for instructions).
