Recently some people have started posting comments on the profiles of historically significant ancestors (HSA), many of which fall within the European Aristocrats Project. They will post (again, as a comment, not in the bio section) something along the line of "(Their Name) is a 24th great-grandniece of (HSA)."
These ancestors have tens of thousands, some millions, of descendants. The comment section would quickly become overwhelmed and the page tremendously lengthy if everyone that descends from them posts their relationship.
I know it's exciting when you can connect to a noble, royal and/or aristocrat from long ago. Feel free to place these notations on your profile page, within your biography, not on the page of the ancestor. You can put as many as you'd like on your profile page, with a link to the ancestor.
