I like Roche,but pronounced the way it's supposed to be.... if they are pronouncing it "
Rocky", then I'd say stick with Rockey. At least there will be no mispronunciations, just misspellings. My gosh, what a kerfuffle... very interested to see how this one turns out!
I vote for Rocher.... like the chocolates ;) And that way her name is "Rocker"! *does air guitar* Righteous!
