A few things here.

Regarding Ursula and Hercules: In Greek Mythology, only a child of a human and a god or goddess is a demigod, if a god had a child with a nymph, for example, that child is not considered a demigod, they are either a nymph or something else entirely. Ursula is implied to be a child of Posiden and a mermaid (which fits with who Posiden slept with in Greek Mythology) and would probaly just be a mermaid for species.

Regarding species: It is entierly possible that any magic species that can breed with humans is actually a sub-species. The modern human is actually called Homo sapiens sapiens because sub-species are a thing that could happen or did happen in the past. The writers would have to decide if they want to go with this or not, but it would work, so for example, the scientific name for fairies would be Homo sapiens fey and for genies would be Homo sapiens djinn. In this case, the child of a Homo sapiens sapiens and a Homo sapiens fey could still be a Homo sapiens sapiens. Given what we have seen of Rumple, I think for the time being, we have to assume he is a normal human, until we have proof otherwise.
