LOL, this theory can't be serioius. Both the manga and the Attack on Titan Guidebook confirm that Armin's parents died during the failed operation to retake Wall Maria one year after the fall of Shiganshina (it says Wall Rose but it was actually Maria):



But even if it hadn't been confirmed, this theory is incredibly illogical. I don't know how its supporters can think that neither Armin nor Erwin would be able to recognize each other when Armin joined the Survey Corps. We know Erwin has been in the Corps since at least 837 and his appearance has barely changed, and Armin always has had his coconut as far as we know, so upon their first meeting any of them should be able to say "Hey, father/son! What's up?". I don't think they suffer from Dory's syndrome or something like that. :/ Plus as you just said, Isayama himself confirmed that Erwin always remained single.
