If we aren't going to mark him as a hybrid because we don't know how fairy blood works, his species should be unknown, because by that logic we do not know his species. We also have to change all of the fairies' pages to change their species to unknown. And Ursula's, since we can't assume that she's a demigod. Heck, go ahead and change David's - we don't know his dad, so how can we assume he's human?

Okay, that's kind of a slippery slope argument, which makes me a bit of a hypocrite. But still - claiming we can't list something apparently obvious because there's a possibility it's wrong is flawed logic. We could find out next week that Snow White actually isn't Eva and Leopold's daughter. We could find out next week that Emma doesn't really exist and that she's in everyone's imagination! But we wouldn't change the pages to reflect that these things are possible because... well, that's dumb.

Here's what we know: the Black Fairy is a fairy. Rumplestiltskin was born to her and a human male. That makes Rumplestiltskin half-fairy. We could read more into it and claim that there's a chance that fairies aren't a separate species, but that's never been outright stated by any official material.

As for Ursula's former species... I think we should mark her as unknown. Technically, we don't know if her mother was mortal - she could be full-deity. We don't know enough of her heritage to infer a species, unlike Rumple. I agree with your points. But I think it was stated that Ursula's mother was killed by pirates, so we can infer that she's not a diety.
