I pronounce it like Eloise, but with an H.As for the name itself, I don't like Heloise. Eloise is pretty, and the H at the beginning makes it kind of ugly (and witchy).
Like Eloise I presume, because I think the 'H' is silent in France. (Like they pronounce 'hospital' as 'ospital' I think.)Correct me if I'm wrong please.
