[Opinions] Re: Isild/Isilda/Isilde
Isilda looks to me like one of those Latin American mashup names - Isabel + Hilda maybe? and the INSEE data for Isilde / Isild in France suggests that it's a recent invention. I like all three of them - especially as they remove the 'is old' problem with Isolde etc. in English. Lacking in combos though, sorry!
