Anonymous2: Canon? Any relationship possibilities are predetermined in Marth's games; they don't have supports (those didn't exist until Roy's game), so the only way to influence relationships is to kill off people. Marth's a sad panda if Sheeda/Caeda doesn't survive to the ending, for example.
In any case, Maria's the younger sister of Minerva (which, given FE's recurring sibling incest theme, you'd think would give them a better chance), and there's not anything remotely romantic in text for either of them. On the other hand, you can take Minerva's protectiveness of little Maria as far as you want.
