very few of the characters are what I would consider orphans. David had his mom until his wedding. Snow is debateable, as she had her dad until she was grown, or at least mostly grown. Regina had her dad until the dark curse, and then her mom even after that. Belle had her dad. Henry has 2 moms, and only lost his dad recently. We know nothing of Robin's background, yet. A case could be made for Zelena, but she was not technically an orphan, though she was abandoned, she did have a family that raised her, and only when she was grown did she find out that they were not her birth family.

That leaves Rumple, Emma, and Killian from the main group. Rumple was abandoned by his dad when he was young, and had lost his mom earlier (or so we all imagine, we actually know nothing of Rumples mother), so though he is technically not an orphan (he knew exactly who his dad was), he was raised as one. Emma has BOTH of her parents, but was raised as an orphan in our world. And, unlike Zelena (or Lily for that matter), Emma never had a family.

Killian, we know that he was abandoned by his father when he was young, and we know nothing of his mother. He, at least for now, seems to be in the same situation as Rumple (other than the fact that Killian did have his older Brother).

I guess the point of all of this is that Arthur is the only truly confirmed orphan in the lot. Rumple and Killian come close (and maybe with a revelation of Killian's backstory we'll find out more details), and that's it.
