I like that actually @Merit.
Perhaps point out that various clans do indeed draw from many many different cultures, (fantastical and not).
I'll borrow the concept from elfquest: Wolfrider's have a 'public' use-name. "Cutter" (for quickwit & skill with a sword), but also a soul name (that only the closest to them know- their parents, their spouses, Cutter's 'Tam'.), His soulBrother ,Skywise's soul name is Fahr, but when Cutter met his life mate.. She doesn't have a soul name (she's not a wolfrider, there is no need to 'hide' who she is). He basically goes: All I found... was Leetah ( her name, which means 'Healing Light'-).
So why not just say: that the Fae have public names & private names, and the idea of Masks & Personae are common amounts them.
One Winter Fae, could easily be 'Lady Iceheart' when acting in a judge capcity,-it's both a title and name, but to her friends is Ysalye' ( Ok so I totally took that from Final Fantasy XIV, but I make my point.)
A varity of 'names' & titles and monikers, for a variety of occasions, which makes influence their look. or outward 'appearance' slightly. You can still tell who they 'ARE', that isn't hidden from you, as a Fae. But then again Fae probably also go through changes from childhood they maybe called one, thing, and grow some and gain a deed, or use name, that sticks to them like gule, so strong is the resonance with their person, and then still later they grow more and gain a proper 'adult' title, and name, but people still use say that childhood/teen name, to indicate a closer association.
