Hopefully to clear up a point of confusion, Ulrich and Elisabeth were the first "parents" linked by the profile manager. When I contacted the profile manager and explained why Ulrich and Elisabeth could not be his parents, she responded by changing the parents to two completely different people: Melchior Ruch and Elisbeth Frauchiger. But those people are not sourced either, and they are all in a completely different country.
The profile manager created this through a gedcom import (don't get me started) with no sources. I am not the profile manager. I'm not sure why I am expected to provide sources for information someone else put in a profile they created.
I only know that whether the parents are linked to Ulrich and Elisabeth, or to Melchior and Elisbeth, it's wrong. To be more precise, the person who made that link has not proved it is right.
I was only asking whether people feel comfortable disconnecting parent links that have no sources. I got a range of answers, but I tend to agree that the yellow text box is the best way to deal with it. I can see how deleting links unilaterally would be considered rude.
