FamilySyncTM Yes, you can take it with you. (Your laptop.)

One of the things that may take some getting used to in using FamilySync instead of TreeSync is that you no longer need to break links. Almost ever. That's because each Ancestry tree can now link to multiple FTM trees, so it's just no longer necessary to break an old link to download a tree to a second computer. Or a third.

So if you’ve got a laptop and a desktop, and you’d like to take Family Tree Maker on the road with you, no problem. You can put your tree on both computers, and sync them both to the same Ancestry tree. Yes, at the same time. So after your trip, you’ll be just one sync away from the happiest (and easiest) family history homecoming you’ve ever had.

Three computers. One Ancestry tree. No problem.
