Hi Susan,
the short answer to your question is, you now go and merge each of the parents.... then repeat this for each duplicated profile in your tree. It's easier if you start merging as "high up" (i.e. back in time) as you can, and working down, one branch at a time.
This might seem like a lot of work, but it's well worth it. After all, that is precisely how we all together created an interconnected forest of trees, with ~46 million people in it.
If you have any additional questions, feel free to ask.
