Too much speculation and personal opinion

Bit of a late reply, but...

Yeah, I agree with Pyro. Deleting this page goes against the reason for the wiki's existence in the first place - efficiently conveying wanted Mabinogi information to players.

As for notability...I did already say these tidbits are notable because they clear up any potential confusion from the inconsistencies. You did take a vote, but if I remember correctly, the only reason that so far against Shakespeare's trivia is that "it's of minor importance" (which sounds like an opinion to me), and the sole reason as of now against Lugh (and Cromm)'s re-entry is that they're not gods (which we've decided they're not, but that has no correlation with them being placed inside the trivia section to note they've been "called" gods). It's true that so far, community opinion is swayed against those two trivia points, but I have to admit I'd be hesitant to act on that without logical justification.

(Though, it doesn't have to be under "Trivia", I'm fine with Saiyr's solution as well.)

Accuracy is pretty important too. Being as accurate as possible can mean looking at both sides of a distinguishing barrier and/or specifying.
