I have a family tree completed for my maternal and paternal ancestors . I now wish to start a new project on a different branch of relatives.
How do I start . In other words where do I go to get a new blank canvas
There are no separate trees in Family Tree. It is a connected tree. However, if you want to enter a record for someone who is not in Family Tree and you do not know any relationships there is a place to do that. If you are on a person page or a pedigree page and you click recents at the very bottom is an option to add an unconnected person. You could begin a branch by adding an unconnected name. You should be aware that if you enter names that are duplicates of names already in the Tree the system will indicate that there are possible duplicates. If duplicate records are found they should be merged.
@EamonnO'Donohue - Here is a Knowledge Article concerning adding an unconnected person. Hope this helps.
As gasmodels stated, there are no blank canvases in Family Tree, just the one huge mural we are all working on together. If you do add an unconnected person to Family Tree, that is that you do move to a spot on the canvas that doesn't have any paint on it yet, keep in mind that your goal should be to hook that part into the main painting as soon as possible.
To change analogies, if you add a single leaf to Family Tree, your first goal should be to connect it to the main tree.
Before you add that new, isolated leaf, be sure to search thoroughly in Family Tree to make sure that person isn't already there.
