Perhaps i'm wrong, but it seems to me, that the only way to get rid of this plague of duplicates and triplicates (most of which are sourceless gedcom-uploaded profiles) is to start merging. Begin with the merger of duplicates of one member of the family, usually the husband or the wife. At least that way Relationship Finder will immediately be able to begin to connect the descendants to one another. After the one spouse, then the other spouse. After them, the children can be merged. Ideally, the duplicate members of a whole family might first be prepared for merging, by clearing the gedcom-uploaded profile of all junk, then trying to make the biographical data of the to-be-merged profiles to correspond, saving alternative names and dates to their proper places. After that they could then be merged one after the other. The problem is that all these profiles have different managers, who must agree to a merger, which usually makes the ideal preparation and merger scenario impossible. So, the best we can do is to merge duplicate profiles as we come across them and not forget to clean-up after the merger, esp. if we have not prepared the two profiles before the merger. And then patiently wait for the managers of the profiles of family members of the merged profile to respond and approve of further mergers.
