God grief this is dumb, even if she was a TS, how would they know from the birth certificate ? If she was TS, they'd be as much a chance that she'd be the least "manly" person as the most manly; mtf TS run in all flavor of femininity, were not all "butch" or "femme". Beside, from the picture, she doesn't look manly and I've seen plenty of non butch GG's act in their way they are describing. Of course, if she was put in a roomfull of girly-girly, any women who is not will stand out.
There's still plenty of stereotype of about how TS appear, and even after the debacle last year of a beautiful girly mtf TS being offered as object of desire, without them knowing.
