merging people on trees

[B546846]

I accidentally created the same person as a child for two different fathers. I can't delete either or I lose branches of the tree.
How can I merge he two individuals into one under the correct father.

This is an excellent example of why you should build your tree using a genealogy program. Create a GEDCOM with the program and then upload it to FTDNA. Problems are much easier to correct in the program, you can produce all kinds of reports and you can create GEDCOMs to share with others.
