1. Creating a Fan Chart on FamilySearch.org
Log into or create a free account on FamilySearch.org. Once you have logged on, you should see halfway down on the main page, an icon that says Fan Chart. Click on the Fan Chart icon. It should pull up a fan chart of your four generations. You should be in the center. You can click on the printer icon and print off a copy of your fan chart. I found this to be a fun way to look at your ancestors.
2. FamilySearch Mobile Memories helps you capture priceless family moments to preserve and share with family now and into the future. It works anywhere—even when you don’t have Internet access. Here's a great tutorial on how to use the app. What I like best about this app is that you can take pictures of family memories and they are stored forever in the FamilySearch vaults. You are able to use the audio feature to record your ancestors life stories. I wish that I could have used this app to record my grandfather's experiences of growing up in South Dakota with the indians. He had the greatest stories!
3. Puzzilla This is one of my favorite tools. Puzzilla uses the information you have in FamilySearch to create descendancy lines. Here's a quick tutorial from FamilySearch showing how Puzzilla works.
4. Billion Graves Camera app
I just downloaded this app tonight. With this app you are able to collect photos of headstones in your local cemetery and then upload the mapped-out photos to the Billion Graves website where you can transcribe the information on the headstone and share it with others.
