Sean: Unfortunately, it's not always possible to have a name linked to an article if the name does not appear in the first paragraph(s) of an article that are displayed on IMDb. It depends on whether the news source provides the entire article to IMDb's news section or just the first paragraph(s) which are displayed on IMDb.
In this case, it looks like IndieWire/Thompson on Hollywood provided only the first seven sentences to IMDb to have names linked. However, there are no individuals' names mentioned in that part of the article which displays on IMDb. The only person mentioned in the article before you and your brother's names come up is Sydney Levine, and the article isn't linked to her page either. Nor does the article appear to be linked to any of the people I checked who are mentioned later in the article, such as Atom Egoyan or Randa Haines.
So I don't there is anything that can be done to get you and your brother's name pages linked to this particular article.
