Is there a way to merge one tree into another when I have the same person in both trees? Both trees are on my hard drive. Both trees were created by Exporting a branch from my huge 45,000+ people family tree. When I exported the first branch (let's call it Tree A), it did not include the connecting person's spouses' trees, which I want it to do. So I exported her and her branch (Tree A), then her husband's branch (Tree B), but now they're still in separate trees and I want them in one tree.
