Well, to that theory of M'gann not being Martian Manhunter's niece, there's one problem. Since she had only met Martian Manhunter 5 months ago, which would be about 3 months before "Bereft", it would be impossible for her not to be his niece if 6 months before "Bereft", she was already calling him "Uncle J'onn". Plus, she wasn't surprised to have green skin while amnesiac in that episode, so maybe she either might have been masquerading as a Green Martian for that long or she might actually have some Green Martian descent as well as White Martian descent.
