I am a subscriber to Ancestry (US only) and have a tree with about 2300 people. Right now it is a private tree. I also have a public tree on geni.org. I have many family members contributing to the Geni tree and herein lies the problem. There are times when a branch of the tree grows on Geni and I'd like to move that information to Ancestry. Now, I can generate a GEDCOM on Geni and upload it to Ancestry but I have found no way to merge that into my tree. I tried making the GEDCOM upload a public tree so I could do a "search", find it and merge it that way. But I had no luck that way. I could not find that public tree. So, is the only alternative to add the people in that branch manually, a person at a time? I'd like to think there is a more elegant solution.
