Unlike other genealogy websites, simply uploading a gedcom does not create a family tree. I see you have uploaded your gedcom. To see how to use that file to add your branch to our global family tree, check the Help Index under the Help tab at the top of the page. Look for files under gedcom, especially GEDCompare. Keep in mind this is a shared family tree. You will not be creating a separate tree and you must be careful not to create duplicate profiles to ones already on WikiTree.
