Having your family tree in software on your computer is a good way to safe guard it – as long as you do proper backups. Having it online in Ancestry is probably fine if you back that up by downloading as well. But if you don’t have your subscription to Ancestry any more are you going to miss details? I’m talking about Source Citation details.
In the video below I am filling in some missing details. It is important to be able to refer back to these details sometimes, especially when comparing records. This is the info that Ancestry pays people to transcribe and it’s really what you are paying for. Sometimes records are very hard to read so don’t think that you will be able to just-read-them-later either. I like to paste them into Text Editor to help me easily change the tabs to spaces before pasting into FTM. Be sure to grab those details!
