I've been told .. and have read on G2G ..that the more information you have in a profile, the better it can help others who are either working on that same profile, or who are looking for a person/information .. and that it's not a good thing to delete information.
If it is distracting you, why not MOVE IT to underneath a == Research == header .. or make a header for === Other notes === (or just use bold for '''Other Notes'''). That way the information is still there, but it's not a distraction.
Another point about why it is good to leave it on the profile/s .. IF the parents have not yet been added to Wikitree, having their marriage information available makes it easier for whomever decides to add the extra profiles.
