My genealogy research began years ago, long before Wiki Tree existed, so my family tree, research notes, originals and copies of original records, etc., are all kept in files in my home. That information has also been entered into Roots Magic that I use for electronic safe-keeping and editing. The profiles that I have or connect to on Wiki Tree came from the information that has been researched and is sourced. I do not rely on Family Search because it's known to be riddled with errors and duplicate profiles for individuals. Unfortunately, the same is true on many profiles on Ancestry and here on Wiki Tree, too. I don't use Ancestry because I take issue with the way they do business, but that's a whole 'nother ball of wax. In Roots Magic I add scans of documents, photos, make notes and add personal information that I don't want to include on a publicly accessible website, and make each of my ancestors' profiles as personal as possible, rather than just a list of their names, birth and death information. I can run reports and customize them, too, in addition to printing them. This is helpful when putting together ancestry books for family members who have requested information on our ancestors. Those are some of the reasons why I prefer to keep my most up-to-date and sourced family tree in electronic format on my computer at home. It works best for me that way.
