I have been given a family tree that may or may not be related to mine. What would be the best way to add this family (several generations) to my info so that at some point, if we're able to find a connection, I can then merge this family into mine? Would I want a separate dataset that eventually can be merged into mine? If this family is related, it doesn't appear that there will be any duplication -- just that my 3rd great-grandfather may have had (or probably had!) siblings, one of which would be the head of the family tree I have been given. We're not sure yet how we're going to be able to determine this since that generation never came to the U.S. Thanks in advance.
