For our kids, we wrote down a small set of rules :

• french origin (with my very french and common surname, living a in french-speaking country)
• kind of rare (I have a very common firstname)
• that would go well or be used in english as well
• that would survive the atrocities of the local heavy accent (teachers and so on…)
• not too long, easy to write
• aesthetically pleasing when written down
