Genealogy, or the art of family tree investigation, has been something of a resurgence in popularity in recent years. There are now a large number of programs that can be used to research and create your family tree, and Reunion for Mac is one of the most popular.
There is also a companion iPhone and iPad app available that can be used to take your family tree data with you when you travel. Having created your family tree on your Mac, complete with notes, images, documents and links, you can then use your mobile device to use that data when away from home.
As well as enabling you to show your family tree to others, or simply read through some of the documents you have attached to your tree, Reunion for iPhone and iPad can also be used to edit your project on the move.
Any changes you do make in the app can be easily merged with the master family tree on your Mac so your updates are immediately reflected. Being so portable, this version of Reunion is idea for taking with you on research missions to the library or when visiting family members.
