wow i guess everybody is talking about the villagers and the one that has a belmont bloodline XD it's really weird to be anybody than daniela, (or danielle) why could she be it?
well i wouldn't say she is of belmont, she could be of any clan, like morisses, renards, or any other else, but from what i have read in wikipaedia that OoE was set after SOTN after 1800's so at that time alucard is asleep (not knowing of Ecclesia) richter might have been dead but had some descendants and so daniela mentioned to Shanoa that she and her grandfather (whoever that guy is) took some monster hunting and PRACTICE (specially at the tristis pass) so, it might be that she was supposed to be the next heroine for the belmont and the new castlevanian heroine as well, but the fact that she's almost 90 years old she wasn't aware about the coming of dracula and also the betrayal of barlowe to shanoa and albus

i hope it makes perfect sense...
