Only some of the senior Council. If Bob is really ~1000 years old, Rashid and maybe Ancient Mai are the only compelling candidates. Most of the rest would have been born in the late 1600's / early 1700's.
I'm not sure if the wording means someone who has appeared live on page, though, or the original Merlin might qualify. PT did pretty much drop that he had a romantic history with Mab
Heck, if Jim had to lie about OG Merlin being the unnamed British prisoner to preserve a major plot point, he would have appeared on page anyway.
@vulture of course it did something, she had him unmake the mantle, cleansing it and then ritually had him remake it. Consort, he with whom they mate, make babies? It's not at all the usual way of transferring the mantle, as she'd previously given it to Maeve to hand out, and Aurora gave it to lily. Neither of which could ahh mate. So she has him go through the process of unmaking the mantle on the table, which transfers power not the form of it, meaning she'd have to remake it, it being remade through sex is highly suggestive esp combined with him being the consort. The ritual itself had purpose. It's almost like she planted an embryo, and I'd point out, despite bonnie's natural growth, he didn't start getting pressed for mental room(ie headaches) until after he had the mantle. Their wasn't enough room for both.
Or coming at it from another angle, she's the queen, she's had sex, even children, but she's not automatically the mother.. because she has to birth an entity into this world, not a human. The mothers are the mothers because they split a portion of themselves off and handed it down to the courts, literally giving birth to them(hence why mother is only the name associated with their fae identity).
I predict Harry will take Molly's virginity, freely given by the person but resisted by the mantle and in doing so, in an act of love, will break the mold giving birth to.. well, whatever. In the vein of everything similar between Odin and Harry(like now the spear, which was predicted correctly off of the same principle btw) Harry is now beefy AF as the WK, (as opposed to a lean runner which harry was in his younger days, same as Odin... and that damned wolfish smile is showing up an awful lot recently...)which matches Odin as Kringle. All that's left is for him to break off an identity all his own for it
when it becomes its own thing, that's when she's Mother in the technical sense. The mothers gave birth to the courts, which per SK ARE the queens, like entirely. So when the courts give birth..
