to be clear...
the gedcom that created that profile has been deleted a long time ago. WikiTree only stores them for about 30-60 days.
but the profile(s) created from it can't be deleted. They can be edited or merged.
Gedcom's are not family trees. They are merely transfer files to move tree information from one genealogy app to another. Be warned, that not all info will transfer (neither in the export, nor in the import), regardless of which app you use.
