Eleanor = the French form of the Provençal name Aenor, plus Alia = other. OK? The other Aenor. Interesting approach to baby naming ... but not unheard-of. So far, so good.
But, where does Aenor come from? Eleanor of Aquitaine's mum was presumably not the first person to have it ... or was she? As the mother of the world's first Eleanor, who knows what else she might have achieved?
Anyone ... ?
