CITATION NEEDED?!!!
I guess we'll never know.
Although the posters being son and father make this funny, it’s apparently very annoying for people on Wikipedia that editors require citations in the form of things like articles.
Emily St J Mandel was (naturally) very upset that her Wikipedia article showed her married to a man, when she was in fact divorced from him and had a girlfriend. She did not wish for her ex to be associated with her name, implying they were married, but investigation proved the only way to change it was to have an article published referring to her divorce that she could cite.
