Just remember, they will be applying for jobs one day, and it is already documented that people emailing identical resumes, one with a usual name, one with an unusual name, get many more responses from the usual names. Use a usual name for first and an unusual one for middle - they can always go by their middle names if they WANT to be unusual, that way.
On the other hand, if the caller on the phone asks for, um, hesitation, you can hang up because if they knew you, they'd know how to pronounce your name.
