Do we by any chance know if Sunok's last name is Fischbach? I was thinking of listing a surname instead of just living it as Sunok (looks kinda plain), but I don't think we know if she ever took the name Fischbach and if she did, did she keep it after her divorce.
I would rather have all links like these to go to an official dev page or social media instead that has these links (like this, and I see it's possible to upload it there in "Files" section") if possible, "X Wiki" or blogs or at worst at this wiki forum where they're visibly validated and better preserved, and then link to there. This isn't a game hosting website, we're at most obliged to only describe the differences.
In short, if a gamepedia wiki has the template or the redirect table to other websites, including gamepedias, otherwise it will have to pass through Gamepedia Help, which for the most of gamepedias only has these shortcuts. When in doubt:
