Ronald, that's precisely the way it would work, except that Johann's profile has no connections at all - no parents, siblings, spouses, or children - and it is completely empty other than birth and death dates/places. The profile came from a gedcom import with an annotation that it is from an "unsourced family tree" that was handed down to the profile manager.
If you have sources for additional information and/or family members, it would be wonderful if you could contact the profile manager about correcting the LNAB (Last Name At Birth). You can add your sources, since the profile is open, and you can also add profiles for the rest of his family.
